UNIVERSAL DC/DC CONVERTER
Description
Features
The AP34063 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 is specifically designed for incorporating in
Step-Down and Step-Up and Voltage-Inverting applications with
a minimum number of external components.

Vsat = Saturation voltage of the output switch.
VF = Forward voltage drop of the output rectifier.
The following power supply characteristics must be chosen:
Vin - Nominal input voltage.
Vout - Desired output voltage, |Vout| = 1.25 (1+R2/R1)
Iout - Desired output current.
fmin - Minimum desired output switching frequency at the selected values of Vin and Io.
Vripple(pp) - Desired peak-to-peak output ripple voltage. In practice, the calculated capacitor value will need to be increased due to its
equivalent series resistance and board layout. The ripple voltage should be kept to a low value since it will directly affect the
line and load regulation.
