AP1509  
150kHz, 2A PWM BUCK DC-DC CONVERTER  
Description  
Pin Assignments  
The AP1509 series are monolithic ICs designed for a step-down  
DC-DC converter and have the ability of driving a 2A load without an  
additional transistor, which saves board space.  
(Top View)  
The external shutdown function can be controlled by logic level and  
then go into standby mode. The internal compensation makes  
feedback control have good line and load regulation without external  
design. Regarding protected function, thermal shutdown prevents  
overtemperature operating from damage, and current limit works  
against overcurrent operating of the output switch. If current limit  
function occurs, and VFB is below 0.5V, the switching frequency is  
reduced. The AP1509 series operates at a switching frequency of  
150kHz thus allowing smaller-sized filter components than what is  
required 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 SO-8 package.
