Datasheet
Single-chip Type with Built-in FET Switching Regulator Series
Step-up and inverted
2-channel DC/DC converter
with Built-in Power MOSFET
BD8316GWL
●Description
The BD8316GWL is step-up and inverted 2-channel
switching regulator with integrated internal high-side
MOSFET. With wide input range from 2.5~5.5V ,it
suitable for application of portable item. In addition,The
small package design is ideal for miniaturizing the
power supply.
●Features
■ Wide input voltage range of 2.5V to 5.5 V
■ High frequency operation 1.6MHz
■ Incorporates Nch FET of 230mΩ/22V and Pch
Pow FET of 230mΩ/15V
■ Incorporates Soft Start (4.2msec(typ))and hight
side switch of boost channel
■ Independent ON/OFF signal(STB). Built-in
discharge SW for step up channel
■ Small package UCSP50L1( 1.8mm×1.5mm, 4×
3 grid, 11pin, WLCSP)
■ Circuits protection OCP,SCP,UVLO,TSD
