General Description  
Features  
The TD7580 is a 240 KHz fixed frequency  
monolithic step down switch mode regulator  
with a built in internal Power MOSFET. It  
achieves 4A continuous output current over a  
wide input supply range with excellent load  
and line regulation.

Up to 95% Efficiency  
Fixed 240KHz Frequency  
Wide 3.6V to 23V Input Voltage Range  
Output Adjustable from 1.222V to 21V  
Built in Frequency Compensation  
Built in Thermal Shutdown Function  
Built in Current Limit Function  
SOP-8 Package is Available  
The minimum dropout up to 0.3V  
The device includes a voltage reference,  
oscillation circuit, error amplifier, internal  
PMOS and etc.  
The PWM control circuit is able to adjust the  
duty ratio linearly from 0 to 100%. An enable  
function, an over current protection function  
and a short circuit protection function are  
built inside. An internal compensation block  
is built in to minimize external component  
count.
