H1563P / H1563S
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 compensated reference, comparator, controlled duty cycle oscillator with an active current sense circuit, bootstrapped 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
