Description
ROHM’s high efficiency step-down switching regulator (BD9122GUL) is a power supply designed to produce a low voltage including 1 volts from 5/3.3 volts power supply line. Offers high efficiency with our original pulse skip control technology and synchronous rectifier. Employs a current mode control system to provide faster transient response to sudden change in load.

Features
1) Offers fast transient response with current mode PWM control system.
2) Offers highly efficiency for all load range with synchronous rectifier
   (Nch/Pch FET) and SLLM™ (Simple Light Load Mode)
3) Incorporates soft-start function.
4) Incorporates thermal protection and ULVO functions.
5) Incorporates short-current protection circuit with time delay function.
6) Incorporates shutdown function
7) Employs WL-CSP : VCSP50L2

Use
   Power supply for LSI including DSP, Micro computer and ASIC
