Digital Controller for Isolated Power Supply Applications ADP1043
PRODUCT OVERVIEW
The ADP1043 is a secondary side power supply controller IC that is designed to provide all the functions that are typically needed in an isolated ac/dc or dc/dc control application. The ADP1043 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, 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, UVLO, and OVP (overvoltage protection). The built-in EEPROM provides extensive programming of the integrated loop filter, PWM signal timing, inrush current, soft start timing and sequencing. Reliability is improved through a built-in checksum and redundancy of critical circuits. A comprehensive GUI is provided for easy design of loop filter characteristics and programming of the safety features. The industry-s……
