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).
The built-in EEPROM provides extensive programming of the
integrated loop filter, PWM signal timing, inrush current, and
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 I 2 C bus provides access to the many moni-
toring and system test functions.
The ADP1043A is available in a 32-lead LFCSP and operates
from a single 3.3 V supply.
