AP2008  
PWM Buck Controller  
„ Features  
„ General Description  
- PWM Buck Control Circuitry  
The AP2008 integrates Pulse-Width-Modulation  
(PWM) control circuit into a single chip, mainly  
designs for power-supply regulator. All the functions  
included an on-chip 0.77V reference output, an  
error amplifier, an adjusted oscillator, a soft-start,  
UVLO, SCP circuitry, and a push-pull output circuit.  
Switching frequency can be adjustable by trimming  
CT. During low VCC situation, the UVLO makes  
sure that the outputs are off until the internal circuit  
is operational normally.  
- Operating voltage can be up to 20V  
- Under voltage Lockout (UVLO) Protection  
- Short Circuit Protection (SCP)  
- Soft-start circuit  
- Variable Oscillator Frequency -- 300KHz Max  
- 0.77V voltage reference Output  
- 8-pin PDIP and SOP packages  
„ Applications  
- Backlight inverter  
- LCD Monitor  
- XDROM, XDSL Product  
- DC/DC converters in computers, etc.
