cd00296047 170 W Power Supply With PFC and Standby Supply For Flat TV Using The l6564 L6599a and Viper27ln Stmicroelectronics by nanoblack88 is a document available to read on EtoBox.
The document describes a 170W power supply design for flat screen TVs using the L6564, L6599A, and Viper27LN chips. The design has three stages: a power factor correction pre-regulator using the L6564 boost controller, a resonant half-bridge converter using the L6599A to provide 12V and 24V outputs, and a flyback-based standby supply using the Viper27LN to deliver 5V. Testing shows the design achieves high efficiency and meets various regulatory standards for power factor and harmonic distortion.
