AP1512/A  
50KHz, 2A/3A PWM Buck DC/DC Converter  
„ Features  
„ General Description  
- Output voltage: 3.3V, 5V, 12V and adjustable  
output version  
The AP1512/A is a monolithic IC that design for a  
step-down DC/DC converter, and own the ability of  
driving a 2A (3A for AP1512A) 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  
- Adjustable version output voltage range, 1.23V to  
37V+4%  
- 50KHz +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 60V  
- Output load current: 2A (for AP1512)  
3A (for AP1512A)  
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. The AP1512/A operates at a  
switching frequency of 50KHz 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 5-lead TO-220 package and  
a 5-lead TO-263.  
- Low power standby mode  
- Built-in switching transistor on chip  
- TO220-5L, TO220-5L(R) and TO263-5L Pb-free  
packages  
„ Applications  
- Simple High-efficiency step-down regulator  
- On-card switching regulators  
- Positive to negative converter
