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

Iout*ton / VRipple(P-P)
Vsat: Saturation voltage of the output switch. VF: Forward voltage of the ringback rectifier. The following power supply characteristics must be chosen: Vin: Nominal input voltage. Vout: Desired output voltage. |Vout|=1.25*(1+RB/RA) Iout: Desired output current Fmin: Minimum desired switching frequency at selected values for Vin and Iout. VRipple(P-P): Desired peak to peak output ripple voltage in practice, the calculated value will need to be increased due to the capacitor equivalent series resistance and board layout. The ripple voltage should be kept to a low value since it will directly effect the line and load regulation.
