AP2004  
PWM Buck Controller  
„ Features  
„ General Description  
- PWM Buck Control Circuitry  
The AP2004 integrates Pulse-Width-Modulation  
(PWM) control circuit into a single chip, mainly  
designs for power-supply regulator. All the functions  
include an on-chip 1.25V reference output, an error  
amplifier, an adjustable oscillator, a soft-start,  
UVLO, SCP circuitry, and a push-pull output circuit.  
Switching frequency is adjustable by trimming CT.  
During low VCC situation, the UVLO makes sure  
that the outputs are off until the internal circuit  
operates normally.  
- Operating voltage can be up to 27V  
- Under voltage Lockout (UVLO) Protection  
- Short Circuit Protection (SCP)  
- Soft-start circuit  
- Variable Oscillator Frequency -- 300Khz Max  
- 1.25V voltage reference Output  
- 8-pin PDIP and SOP packages  
„ Applications  
- Backlight inverter  
- LCD Monitor  
- XDROM, XDSL Product  
- DC/DC converters in computers, etc.
