TITPS62175DQCR
Overview
The TPS62175DQCR is a high-efficiency synchronous step-down converter designed for applications with input voltages up to 28V. Utilizing TI's DCS-Control topology, it provides excellent transient response and high output voltage accuracy while supporting output currents up to 500mA. It is unique for its ability to be configured in both buck and buck-boost (inverting) topologies.
Why Choose This Part
The DCS-Control technology enables a seamless transition between PWM and Power Save modes, maintaining high efficiency across the entire load range. It supports a wide input voltage range from 4.75V to 28V and offers 100% duty cycle mode for very low dropout operation. The 10-pin WSON package includes an active output discharge and a Power Good signal for simplified system sequencing.
Applications
Key Specifications
Getting Started
Engineers can evaluate this part using the TPS62175EVM-098 evaluation module, which demonstrates the typical 1MHz switching frequency and thermal performance. When designing the PCB, ensure the exposed thermal pad is soldered to a large ground plane to manage heat dissipation in high-VIN applications. Use low-ESR ceramic capacitors close to the VIN and VOUT pins to minimize switching noise.
