GENERAL DESCRIPTION
Included on the substrate with the features listed is a high performance trans-conductance error amplifier that provides tight voltage regulation and accuracy under transient conditions. Embedded is Under Voltage Lockout (UVLO) circuit to prevent the device start-up under 4.5V input voltage threshold. In addition, it features an over-current protection and thermal shutdown. To improve the light load efficiency, it is designed as the power saving mode (PSM) to minimize the switching loss by reducing the switching frequency. Application Set-Top-Box, DVD, LCD Display High Power LED Power Supply Distributed Power System Data comm. xDSL CPE Pin Configuration FEATURES
