Product Introduction

TPS40303 High power density, high-efficiency 300kHz 3V to 20V wide input synchronous buck controller

illustrate

The TPS4030x is a cost-optimized synchronous buck controller that operates in 3 - V to 20 V input homes. The controller implements a voltage-mode control architecture with input voltage feedforward compensation that responds immediately to changes in input voltage. The switching frequency is fixed at 300 kHz, 600 kHz or 1.2 MHz.

The increased switching frequency of the frequency jitter spread spectrum function greatly reduces the peak of EMI noise, making it easier to comply with EMI standards.

The TPS4030x offers user-programmable features including soft-start, overcurrent protection (OCP) levels, various designs, and loop compensation.

The level of OCP may be connected to the ground resistor of the circuit by an external program from the LDRV pin.
