HIGH-EFFICIENCY DC/DC CONVERTER

Description

The H1563 is a monolithic control circuit containing the primary functions required for DC to DC converters

and highside-sensed constant current source. The device consists of an internal temperature compensa-

ted reference, comparator, controlled duty cycle oscillator with an active current sense circuit, bootstrap-

ped driver, and high current output switch. This device is specifically designed to construct a constant

current source for battery chargers with a minimum number of external components. Bootstrapped driver

can drive the NPN output switch to saturation for higher eff-iciency and less heat dissipation. The H1563

can deliver 1.5A continuous current without requiring a heat sink.

Features

• 3V to 40V Input Voltage Operation

• Internal 2A Peak Current Switch

• 1.5A Continuous Output Current

• Bootstrapped Driver

• High Side Current Sense Capability

• High Efficiency (up to 90%)

• Internal ±2% Reference

• Low Quiescent Current at 1.6mA

• Frequency Operation from 100Hz to 100KHz

Applications

• Constant Current Source for Battery Chargers

• Saver for Cellular Phone

• Step-Down DC-DC Converter Module
