This application note describes the design procedure of a low power cell phone battery charger using the STD1LNK60Z chip. The charger employs the ringing choke converter (RCC) technique, which offers simple and low-cost implementation.
This document serves as an application note detailing the design of a Ringing Choke Converter (RCC)-based, self-oscillating fly-back converter for cell phone battery charging. It focuses on the use of the STD1LNK60Z MOSFET to create a cost-effective solution for low-power applications.
The system must operate at a frequency of at least 25kHz.
