Datasheet 2A 380KHZ 20V PWM Buck DC/DC Converter TD1410 General

Description

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. The TD1410 serves as ideal power supply units for portable devices.

Pin Number 1,6, 8 2 3 4 Pin Name NC Vin SW GND

Description

Not Connect. Supply Voltage Input Pin. TD1410 operates from a 3.6V to 20V DC voltage. Bypass Vin to GND with a suitably large capacitor to eliminate noise on the input. Power Switch Output Pin. SW is the switch node that supplies power to the output. Ground Pin. Care must be taken in layout. This pin should be placed outside of the Schottky Diode to output capacitor ground path to prevent switching current spikes from [ … ]
