AP1501  
150KHz, 3A PWM BUCK DC/DC CONVERTER  
General Description  
Features  
The AP1501 is a fully integrated step-down DC/DC converter,  
with the ability to drive 3A load without the need of additional  
Output voltage: 3.3V, 5V, 12V and adjustable output  
version  
Adjustable version output voltage range, 1.23V to  
37V+4%  
150KHZ +15% fixed switching frequency  
Voltage mode non-synchronous PWM control  
Thermal-shutdown and current-limit protection  
ON/OFF shutdown control input  
Operating voltage can be up to 40V  
Output load current: 3A  
driver components. The AP1501 operates at  
a switching  
frequency of 150KHZ enabling the use of small size filter  
components. As a result, board space is reduced and BOM costs  
are lowered.  
The AP1501 has integrated the shutdown function that allows  
standby mode to be activated via an external logic signal input.  
The internal compensation facilitates feedback control for line  
and load regulation without the need of an external circuitry. The  
AP1501 has a built-in Thermal shutdown and Current Limit  
function to prevent damage from high operating temperature and  
high current operating to the output switch.  
Low power standby mode  
Built-in switching transistor on chip  
Lead Free packages: TO263-5L and TO220-5L(R)  
TO263-5L and TO220-5L(R): Available in “Green”  
Molding Compound (No Br, Sb)  
Additional features include a guaranteed +/- 4% tolerance on the  
output voltage under specified input and output load conditions,  
and +/- 15% on oscillator frequency. The AP1501 offers both  
fixed and a Adjustable output voltages. For fixed outputs the  
AP1501 supports 3.3V, 5.0V and 12V. The package options  
available are standard 5-lead TO263 and TO220(R) packages.  
Lead Free Finish/RoHS Compliant (Note 1)  
Applications  
Simple High-efficiency step-down regulator  
On-card switching regulators  
Positive to negative converter
