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.
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.
ROHM CMOS camera module power supply ICs feature 80% efficiency and a standby current of 0µA. Optimized for CMOS camera systems requiring 2 outputs, full compensation and feedback resistance are built in, reducing mounting area as well as mounting and processing costs. In addition, the integrated sequence control circuit enables startup of multiple voltage sources using only a few external components.
ROHM CCD camera module power supply ICs feature 75% efficiency and a standby current of 0µA. Optimized for CMOS camera systems requiring 3 outputs, full compensation and feedback resistance are built in, reducing mounting area as well as mounting and processing costs. In addition, the integrated sequence control circuit enables startup of multiple voltage sources using only a few external components.
