FEBFAN302HL_CH442v1 • Rev. 1.0.0
1. General Introduction
This document describes a 5W power supply using a FAN302HL device. This power
supply is targeted for mobile phone battery chargers with a 10mW solution and requiring
high efficiency.
To get the standby power consumption lower than 10mW at 230V
AC
, the FAN302HL has
functions to enhance the standby power consumption, including proprietary Burst Mode
with lower operation current under light-load conditions and built-in HV startup circuitry
in the IC side to reduce startup resistor power loss.
Using FAN302HL, a charger can be implemented with the few external components and
minimized cost.
