AP1509  
150KHz, 2A PWM Buck DC/DC Converter  
„ Features  
„ General Description  
- Output voltage: 3.3V, 5V, 12V and adjustable  
output version  
The AP1509 series are monolithic IC designed for a  
step-down DC/DC converter, and own the ability of  
driving a 2A load without additional transistor. It  
saves board space. The external shutdown function  
can be controlled by logic level and then come into  
standby mode. The internal compensation makes  
feedback control having good line and load  
regulation without external design. Regarding  
protected function, thermal shutdown is to prevent  
over temperature operating from damage, and  
current limit is against over current operating of the  
output switch. If current limit function occurs and  
VFB is down below 0.5V, the switching frequency  
will be reduced. The AP1509 series operates at a  
switching frequency of 150KHz thus allow smaller  
sized filter components than what would be needed  
with lower frequency switching regulators. Other  
features include a guaranteed +4% tolerance on  
output voltage under specified input voltage and  
output load conditions, and +15% on the oscillator  
frequency. The output version included fixed 3.3V,  
5V, 12V, and an adjustable type. The chips are  
available in a standard 8-lead SOP-8 package.  
- Adjustable version output voltage range, 1.23V to  
18V+4%  
- 150KHz +15% fixed switching frequency  
- Voltage mode non-synchronous PWM control  
- Thermal-shutdown and current-limit protection  
- ON/OFF shutdown control input  
- Operating voltage can be up to 22V  
- Output load current: 2A  
- SOP-8L packages  
- Low power standby mode  
- Built-in switching transistor on chip  
„ Applications  
- Simple High-efficiency step-down regulator  
- On-card switching regulators  
- Positive to negative converter
