1 Introduction
This document is an engineering report giving performance characteristics of a 5.5 V,
500 mA charger/adapter. The charger uses LinkSwitch – an integrated IC combining a
700 V high voltage MOSFET, PWM controller, start-up, thermal shut down and fault
protection circuitry. The controller provides both duty cycle and current limit control to
yield a constant voltage/constant current output characteristic without secondary-side 字串9
sensing. This power supply is designed to provide a cost effective replacement for linear
transformer based chargers and adapters while providing the additional benefits of
universal input range and high energy efficiency. 专业软件下载
