General Description  
Features  
The TD2676 is a 52 KHz fixed frequency monolithic step 2.5A Constant Output Current  
down switch mode regulator with a built in internal Power 80mRDSON Internal Power PMOSFET Switch  
MOSFET. It achieves 2.5A continuous output current Up to 95% Efficiency  
over a wide input supply range with excellent load and Fixed 52KHz Frequency  
line regulation.  
Wide 3.6V to 32V Input Voltage Range  
The device includes a voltage reference, oscillation Output Adjustable from 0.8V to 30V  
circuit, error amplifier, internal PMOS and etc.  
Built in Frequency Compensation  
Built in Thermal Shutdown Function  
The PWM control circuit is able to adjust the duty ratio Built in Current Limit Function  
linearly from 0 to 100%. An enable function, an over SOP-8 Package is Available  
current protection function and a short circuit protection The minimum dropout up to 0.3V  
function are built inside. An internal compensation block  
is built in to minimize external component count.  
Applications  
The TD2676 serves as ideal power supply units for  
portable devices.
