AP34063
General Description
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.
