AIC1562
High-Efficiency, Bootstrapped DC/DC Converter
FEATURES
3V to 20V Input Voltage Operation.
Internal 800mA Switch.
Bootstrapped Driver for N-Channel MOSFET.
High Efficiency (up to 90%).
Fast Transient Response.
Internal ±2% Reference.
Low Quiescent Current at 1.6mA.
Frequency Operation from 200Hz to 200KHz.
APPLICATIONS
CPU Power Supplies for Mother Boards.
DC/DC Converters for CPU VRMs.
Step-Down DC-DC Converter Module.
DESCRIPTION
The AIC1562 is a high performance monolithic
DC/DC converter drive IC with output-
bootstrapping capability, designed specifically for
driving N-channel MOSFET to achieve maximum
possible power conversion efficiency. The device
consists of an internal temperature compensated
reference, comparator, controlled duty cycle
oscillator, bootstrapped driver and a 800mA output
switch. Working with the AIC1741, a low power
adjustable regulator, the AIC1562 works at 100%
duty cycle under heavy load transient conditions to
minimize transient response time, making it an idea
precision switching power solution to stringent
requirements on computer mother boards.
