AP1501A  
150KHz, 5A PWM BUCK DC/DC CONVERTER  
General Description  
Features  
The AP1501A series are monolithic ICs that are designed for a  
step-down DC/DC converter, and possess the ability to drive a  
5A 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. The AP1501A 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 includes fixed 3.3V, 5V, 12V, and an  
adjustable type. The packages are available in a standard 5-lead  
TO263 and TO220 packages.  
Output voltage: 3.3V, 5V, 12V and adjustable output
