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 230VAC, 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.
