TD1410
TD1410 is 2A 380KHZ 20V PWM Buck DC/DC Converter manufactured by Techcode.
Description
Features
The TD1410 is a 380 KHz fixed frequency monolithic step down switch mode regulator with a built in internal Power MOSFET. It achieves 2A continuous output current over a wide input supply range with excellent load and line regulation. 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 pensation block is built in to minimize external ponent count. z 2A Constant Output Current z 140mΩ RDSON Internal Power PMOSFET Switch z Up to 95% Efficiency z Fixed 380KHz Frequency z Wide 3.6V to 20V Input Voltage Range z Output Adjustable from 1.222V to 18V z Built in Frequency pensation z Built in Thermal Shutdown Function z Built in Current Limit Function z SOP-8 Package is Available z The minimum dropout up to 0.3V
