LC709511F
Power Bank Controller with
USB Type-C & Quick Charge™ 3.0
for 1-Cell Li-Ion and Li-Poly Battery
Overview
LC709511F is a Lithium ion switching charger controller for Power
Bank. This device has all functions to control Power Bank application.
It includes Type-C port control, Quick Charge 3.0 HVDCP and Smart
switch. The built-in switching controller can output from 5 V up to 12 V
for Quick Charge. The high power output for USB Type-C and Quick
Charge is possible with appropriate external MOSFETs.
