Description
ROHM’s high efficiency step-down switching regulator BD9130EFJ is a power supply designed to produce a low voltageincluding 1 volts from 5.5/3.3 volts power supply line. Offers high efficiency with our original pulse skip control technologyand synchronous rectifier. Employs a current mode control system to provide faster transient response to sudden changein 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 SLLMTM(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 function7) Employs small surface mount package : HTSOP-J8
Typical applications
- Power supply for LSI including DSP, Micro computer and ASIC
