150KHz, 2A PWM BUCK DC/DC CONVERTER  
FEATURES  
DESCRIPTION  
The APE1701 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 APE1701 series operates at  
a switching frequency of 150KHz thus allow smaller sized  
filter components than what would be needed with lower  
frequency switching regulators. The output version included  
fixed 3.3V, 5V, 12V, and an adjustable type. The chips are  
available in a standard SO-8 package.
