DESCRIPTION
The AIC1562 is a high performance monolithic DC/DC converter drive IC with outputbootstrapping 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.
