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  
component. Due to reducing the number of external  
component, the board space can be saved easily.  
The external shutdown function can be controlled  
by logic level and then come into standby mode.  
The internal compensation makes feedback control  
have 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 occurred and VFB is down to 0.5V  
below, the switching frequency will be reduced.  
- 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  
The AP1509 series operates at  
a switching  
frequency of 150KHz thus allowing 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 packages are  
available in a standard 8-lead SOP-8 package.  
- Simple High-efficiency step-down regulator  
- On-card switching regulators  
- Positive to negative converter
