AP1509  
150KHz, 2A PWM BUCK DC/DC CONVERTER  
Description  
Pin Assignments  
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.
