A PWM (Pulse Width Modulation) Buck DC/DC Converter is an electronic circuit or device used to regulate and control the output voltage of a power supply by adjusting the duty cycle of a high-frequency switching signal. This type of converter is also known as a step-down voltage regulator because it takes a higher input voltage and converts it into a lower, stable output voltage.
Part Number: TD1410
Function: 2A, 380KHZ, 20V, PWM Buck DC/DC Converter
Package: SOP 8 Pin Type
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 compensation block is built in to minimize external component count.
