ROHM’s New PWM Controller ICs with SOP Package for Power Supply in a Wide Variety of Industrial Applications
  ROHM has developed external FET-type controller ICs utilizing PWM current control mode optimized for AC-DC power supply in various industrial applications. Mass production has begun for four variants designed to drive a wide range of power semiconductors: the BD28C55FJ-LB for low-voltage MOSFETs, BD28C54FJ-LB for medium- to high-voltage MOSFETs, BD28C57LFJ-LB for IGBTs, and BD28C57HFJ-LB for SiC MOSFETs.  Although the global semiconductor shortage is beginning to ease, the supply of semiconductor components for power supplies in industrial applications continues to lag behind demand. This is particularly true for PWM controller ICs, where the limited number of manufacturers has resulted in chronic shortages, leading to numerous requests for product development.  In response, ROHM has developed PWM controller ICs that address the ongoing supply issue by meeting the industrial market’s stringent package and performance requirements. Depending upon the input AC voltage range of the application, a wide variety of semiconductors are used for power supply circuit. Each of these semiconductors demand different undervoltage lock out levels to prevent thermal runaway in case of supply/gate voltage drop. To solve this issue, ROHM has developed 4 variants with different undervoltage lock out levels.  The new products feature an input voltage range of 6.9V to 28.0V, circuit current up to 2.0mA, maximum startup current of 75µA, and a maximum duty cycle of 50%, offered in the standard SOP-J8 package (equivalent to the JEDEC SOIC8). The products are pin to pin compatible to standard products commonly used in power supply circuits, thus reducing re-design and modification efforts. All variants are equipped with a self-recovery-type undervoltage lockout function (UVLO) with voltage hysteresis. This significantly improves application reliability by reducing the threshold voltage error to ±5%, compared to the typical ±10% of standard products.  At the same time, these ICs are designated for long-term supply, thus ensuring continuous operation of long-life industrial equipment. Going forward, the lineup will be further expanded to include products suitable to drive high-voltage MOSFETs and GaN devices. More variants to support a maximum duty cycle of 100% are also being planned.  Application ExamplesIndustrial equipment: AC-DC power supplies, motor drive inverters, and other AC-powered devices  Product Information  Applicable Part Nos: BD28C54FJ-LB, BD28C55FJ-LB, BD28C57HFJ-LB, BD28C57LFJ-LB  TerminologyPWM Control Type  Short for Pulse Width Modulation, a method for controlling power using semiconductors. The output power is controlled by varying the ratio of ON and OFF times within a fixed cycle.  Duty Cycle  The proportion of ON and OFF times as percentage of the switching period is known as ON- and OFF-duty cycle, respectively. It is common to refer to the ON-time ratio as the duty cycle. Duty Cycle (%) = Pulse Width (t) / Period (T).  Self-Recovery Undervoltage Lockout Function (UVLO) with Voltage Hysteresis  This function safety stops IC operation before the circuit inside the IC becomes abnormal when the input voltage drops below a threshold. For self-recovery types, the IC can become unstable by repeatedly stopping and starting near the threshold voltage, so a protection circuit with hysteresis is used to create a voltage difference between the stop and restart points.

ROHM’s New N-channel MOSFETs Offer High Mounting Reliability in Automotive Applications
  ROHM has released N-channel MOSFETs - RF9x120BKFRA / RQ3xxx0BxFRA / RD3x0xxBKHRB - featuring low ON-resistance ideal for a variety of automotive applications, including motors for doors and seat positioning, as well as LED headlights. Sales have begun with 10 models across 3 package types, with plans to expand the lineup in the future.  The automotive sector is seeing a surge in the number of electronic components, driven by the demand for enhanced safety and convenience. At the same time, there is a pressing need for improved power efficiency to optimize fuel and electricity consumption. Especially for MOSFETs essential for switching applications in automotive systems, there is a growing requirement for lower ON resistance to minimize loss and heat generation.  ROHM, which has been supplying low ON-resistance MOSFETs for consumer and industrial equipment, has now extended this technology to the automotive sector. Adapting cutting-edge medium voltage processes to meet the stringent reliability requirements of automotive products allowed us to develop 10 N-channel MOSFET models characterized by low ON resistance.  Offered in voltage ratings of 40V, 60V, and 100V, the new products incorporate a split-gate structure to achieve low ON-resistance, contributing to higher efficiency operation in automotive applications. All models are qualified under the AEC-Q101 automotive reliability standard, guaranteeing exceptional high reliability.  Users can select from among three package types, depending on the application. For space-constrained sets like Advanced Driver Assistance Systems (ADAS), the compact DFN2020Y7LSAA (2.0mm × 2.0mm) and HSMT8AG (3.3mm × 3.3mm) packages are ideal. For automotive power applications, the widely used TO-252 (DPAK) package (6.6mm × 10.0mm) is also available. In addition, ROHM has further enhanced mounting reliability by utilizing wettable flank technology for the DFN2020Y7LSAA package and gull-wing leads for the TO-252 package.  Going forward, ROHM plans to expand its lineup of medium-voltage N-channel MOSFETs to provide even greater miniaturization and higher efficiency in automotive applications. Mass production of the DFN3333 (3.3mm × 3.3mm) and HPLF5060 (5.0mm × 6.0mm) packages is scheduled for October 2024, followed by 80V products in 2025. P-channel products are also scheduled for future release.  Application Examples◇ Vehicle motors (e.g., doors, seat positioning, power windows)  ◇ LED headlights  ◇ Car infotainment / displays  ◇ Advanced Driver Assistance Systems (ADAS)  Internet Sales InformationOnline Distributors: DigiKey, Mouser and Farnell  Pricing: $3.50/unit (samples, excluding tax)  Availability: Now (OEM quantities)  The products will be offered at other online distributors as they become available.  (Sales Launch Date: June 2024)  Online Distributors  TerminologyON resistance (Ron)  The resistance value between the Drain and Source while the MOSFET is ON. The smaller this value is, the lower the (power) loss during conduction.  N-channel MOSFET  A type of MOSFET that conducts when a positive voltage is applied to the Gate relative to the Source. N-channel MOSFETs are more widely adopted in the market today due to their lower ON-resistance (RDS(on)) over P-channel variants, facilitating use in a broad range of circuits.  Split Gate Structure  A technology that divides the gate of the MOSFET into multiple parts to efficiently regulate the flow of electrons. This ensures fast, reliable operation.  Wettable Flank Technology  A technique for plating the sides of the lead frame on bottom electrode packages to improve mounting reliability.  Gull Wing Leads  A terminal structure that spreads outwards from both sides of the package. It achieves excellent heat dissipation along with increased mounting reliability.
