EPR-16 - LinkSwitch 2.75 W Charger/Adapter
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
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.
This document contains the power supply specification, schematic, bill of materials,
transformer documentation, printed circuit board layout, and performance data.
