ADP1043A Digital Controller for Isolated Power Supply Applications

GENERAL DESCRIPTION
The ADP1043A is a secondary side power supply controller IC designed to provide all the functions that are typically needed in an ac-to-dc or isolated dc-to-dc control application.
The ADP1043A is optimized for minimal component count, maximum flexibility, and minimum design time. Features include remote voltage sense, local voltage sense, primary and secondary side current sense, pulse-width modulation (PWM) generation, and hot-swap sense and control. The control loop is digital with an integrated programmable digital filter. Protection features include current limiting, ac sense, undervoltage lockout (UVLO), and overvoltage protection (OVP).

FEATURES
Integrates all typical controller functions
  Digital control loop
  Remote and local voltage sense
  Primary and secondary side current sense
  PWM control
  Synchronous rectifier control
  Current sharing
