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-standard I2C bus gives access to the many monitoring
and system test functions.
The ADP1043 is available in a 32-lead LFCSP package and
operates from a single 3.3 V supply.
