DC-TO-DC CONVERTER INTEGRATE CIRCUIT DEVICES
Description
The H34063A 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.

V

: Desired output voltage. |Vout|=1.25*(1+RB/RA)
I

: Minimum desired output switching frequency at the selected values for Vin and Iout.
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.
