Monolithic Dual Channel PWM Controller

ꢀFeatures

ꢀGeneral Description

- Dual PWM Control Circuitry

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.

- Operating voltage can be up to 50V

- Adjustable Dead Time Control (DTC)

- Under voltage Lockout (UVLO) Protection

- Short Circuit Protection (SCP)

- Variable Oscillator Frequency...... 500Khz Max

- 2.5V voltage reference Output

- 16-pin PDIP and SOP packages

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.

ꢀApplications

- Backlight inverter

- DC/DC converts in computers, etc.
