AN00055: STARplug Efficient Low Power Supply
Application note for the NXP TEA152x STARplug, detailing design procedures for efficient isolated flyback and non-isolated buck converters for low-power and standby supplies.
Overview
This application note provides a comprehensive guide for designing efficient AC/DC and DC/DC converters using the NXP TEA152x (STARplug) controller series. It covers the fundamental operation of both isolated flyback and non-isolated buck topologies. The document details the controller's features, including an integrated 650 V power MOS transistor, high-voltage start-up current source, and adjustable oscillator. It includes a step-by-step design procedure and performance evaluation for a 5 V/3 W reference board designed for universal mains input, targeting high efficiency and low standby power consumption.
Use Cases
- Cellular phone and GSM chargers
- Standby power supplies for consumer electronics
- Low-power AC/DC adapters
- Portable product power management
- High-efficiency non-isolated buck converters
