ROHM's large current external FET controller type switching regulators are compatible with virtually all switching power supply applications due to their wide input voltage range, multi-operation capability (step-up/negative voltage/step-down), and flexible operating frequency.
BD7F series is an optocoupler-less Isolated Flyback Converter. An optocoupler or the tertiary winding feedback circuit which was needed to obtain a stable output voltage isolated by a transformer in the conventional application becomes unnecessary, thus, the number of parts is reduced drastically, producing a small-sized and high-reliability application isolated type power supply. Furthermore, a highly by the use of the Original Adapted-Type ON-Time Control Technology, it makes the external phase compensation parts become unnecessary, therefore a highly efficient isolated type power supply application can easily be produced.
BD8325FVT is a PWM controller intended for Active clamp, current-mode isolated switching regulator.
ROHM's switching regulator series (DC/DC converter) are available with or without integrated FET (boost/buck/boost-buck) and from single-channel to multi-channel system power supply configurations for broad compatibility. ROHM offers industry-leading DC/DC converters and evaluation boards that allow customers to develop and differentiate their power designs. Support videos, application notes, and commentary are also available to provide assistance at every stage of development.

ROHM voltage detector IC series are reset IC with highly accurate detection voltage of ±1% , low current consumption, small thin packages and wide range of detection voltage. They can be used for every kind of application equipped with controllers such as micro controllers, CPU or DSP. In the ROHM voltage detector IC series, both CMOS and open drain output are available, therefore output of reset signal can be selected for connected power supply. Default SSOP packages are pin-compatible and function-compatible, so they can be used as replacement for existing IC. Besides, a lineup of very small and thin package makes compact implementation near micro controllers possible. All lineups are Pb-free, and meet RoHS.
LAPIS Semiconductor's 13.56 MHz wireless charging LSIs, "ML7630" and "ML7361", provide a wireless charging system using the world's smallest chip solution including a downsized antenna by the 13.56 MHz power transfer.
They are a suitable for achieving a wireless charging solution of small devices such as wearables devices up to 0.2W power.
ROHM power management switch ICs integrate a low ON-resistance MOSFET and multiple protection circuits on a single chip,resulting in low loss, high efficiency, and stable, reliable operation - all on a single chip. Ideal for power management in USB memory sticks, expansion modules for PCs, and other digital devices.
The IPD (intelligent power device) series of the ROHM is a universal switch of the automotive grade that integrated low on resistance MOSFET and various protection circuit into one chip. For overheat, an overcurrent, overvoltage and a load short circuit, provide the protection of the higher level. Including resistant capacity-related inducible load installed in the engine room, a compartment, be available in product machine applications.
ROHM offers a broad lineup of LED drivers, such as AC/DC, DC/AC, and constant current types optimized for a variety of applications, including lighting, backlighting, camera flash, displays, and automotive systems.
