General Description
The AP2001 integrates Pulse-width-Modulation
(PWM) control circuit into a single chip, mainly
designs for power-supply regulator. All the functions
included an on-chip 2.5V reference output, two
error amplifiers, an adjustable oscillator, two
dead-time comparators, UVLO, SCP, DTC circuitry,
and dual common-emitter(CE) output transistor
circuit.
Recommend the output CE transistors as pre-driver
for Driving externally. The DTC can provide from
0% to 100%. Switching frequency can be
adjustable by trimming RT and CT. During low VCC
situation, the UVLO makes sure that the outputs
are off until the internal circuit is operational
normally.
