The BD9641NUV 1ch synchronous rectification step-up switching regulator integrates a FET and is compatible with single-cell li-ion voltages (2.5V-5.5V), making it ideal for compact portable equipment. In addition, synchronous rectification results in an industry-leading 96% efficiency at a relatively high load current (approx. 150mA), while the compact package, combined with simpler peripheral circuitry, contribute to smaller power supply systems.

ROHM's lineup of high performance LDO regulators and DC/DC converters integrate a variety of channels on a single chip. A unique disperse power supply element design saves space while making it possible to use only the number of power supplies required for better efficiency. The BH6172GU utilizes original circuit technology for safe, high efficiency driving across all load regions (i.e. 85% efficiency at Io=150mA).

ROHM's original light load control method, SLLM (Simple Light Load Mode), was designed to operate efficiently under light loads for significantly reduced power consumption. In addition, synchronized startup of multiple power supplies is now easier with faster load response (20mV), about half that of conventional products, using the Enable (EN) and Soft Start (SS) terminals.

ROHM offers 24 models in a range of different speeds, power consumptions, packages, and channels to ensure compatibility with a wide variety of sets. 1.8V drive and input/output full swing operation result in efficient driving.

Original precision technology and unique device construction enables simultaneous low V_F and I_R along with high ESD resistance.

Optimizing switching speeds has resulted in a power supply efficiency of 91%. This translates to a 140mW difference at 9V/200mA, or roughly equivalent to the amount of power consumption reduction of 10 conventional opamps.

A variety of lineups are offered optimized for compact, energy-saving power supply configurations, including high accuracy (±1%) units and models integrating multiple protection circuits (i.e. overvoltage, overcurrent,temperature protection).

In order to minimize power consumption the power supply system must operate efficiently at high frequencies. ROHM's DC/DC converters integrate a power MOSFET with low ON resistance utilizing DMOS processes for high-speed switching capability, reducing power consumption.

Even when small currents are superimposed, the load on a battery may become large. In response to this we offer a 30µA low noise current regulator developed using original circuit technology that integrates a P-channel DMOSFET as the output transistor.
