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.
■[High Efficiency] High efficiency even when suspended
Unique SLLM (Simple Light Load Mode) control ensures low power consumption and high efficiency under light loads with, even in suspension mode and during normal operation - 95% over the entire load region.
■[High Speed] Safe operating voltages with high-speed response
Original technologies were developed to responds to high-speed CPU or DRAM load fluctuations in order to secure safe operating voltages by holding the output constant. The result is greater stability at higher speeds and lower voltages.
■[High Performance] Synchronized startup of multiple power supplies
Connecting the Soft Start (SS) and Enable (EN) terminals suppresses parasitic elements and ensures safe startup of multiple power supplies for CPUs and DRAMs.

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.

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.
