Application note

170 W power supply with PFC and standby supply for flat TV

using the L6564, L6599A, and Viper27LN

Introduction

This application note describes the characteristics and features of a 170 W, wide input

mains range, power-factor-corrected, demonstration board for flat TVs or industrial

applications. The electrical specifications are tailored to a typical flat TV.

The architecture is made up of three stages: a front-end PFC pre-regulator based on the

L6564 TM (transition mode) boost PFC controller and a downstream LLC resonant half

bridge converter stage, built around the new L6599A resonant controller, which provides two

regulated output voltages at 12 V and 24 V. In addition, a flyback-based standby supply

delivers 10 W to a 5 V output. Thanks to the chipset used, this design achieves very high

efficiency, compliant with ENERGY STAR® eligibility criteria (EPA rev. 2.0 EPS), as well as

very low input consumption during standby operation.
