H34063AS
DC-TO-DC CONVERTER INTEGRATE CIRCUIT DEVICES
Description
The H34063AS Series is a monolithic control circuit containing the primary functions required for
DC-to-DC converters. These devices consist of an internal temperature compensated reference,
comparator, controlled duty cycle oscillator with an active current limit circuit, driver and high
current output switch. This series was specifically by Hi-Sincerity Microelectronics Corp.
Features
• 3V to 40V Input Voltage Operation
• Internal 1.6A Peak Current Switch
• Internal ±1.8% Reference
• Low Quiescent Current at 1.6mA
• Frequency Operation from 100Hz~100KHz
• Current Limiting
Applications
• Saver for Cellular Phone
• DC-DC Converter Module

Vsat : Saturation voltage of the output switch.

The following power supply characteristics must be chosen :
V
in : Nominal input voltage.
V
out : Desired output voltage. |Vout|=1.25*(1+RB/RA)
I
out- Desired output current
Fmin : Minimum desired output switching frequency at the selected values for V
V
Ripple(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.
