AP1512/A  
50KHz, 2A/3A PWM BUCK DC/DC CONVERTER  
General Description  
Features  
The AP1512/A is a monolithic IC designed for use as a  
step-down DC/DC converter with the ability of driving a 2A (3A for  
AP1512A) load without additional transistor components. The  
board space is reduced since AP1512/A requires few external  
components. The external shutdown function is controlled by  
logic level and can be put into standby mode. The internal  
compensation ensures feedback control has good line and load  
regulation without external design. Both an integrated Thermal  
shutdown and Current Limit function are provided to prevent  
damage from exceeding temperature operation and against  
exceeding the 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%  
tolerance on the oscillator frequency. The AP1512/A offers fixed  
output voltages of 3.3V, 5V, 12V, plus Adjustable. The package is  
available in a standard 5-lead TO263 package.
