Texas Instruments TPS543C20A | Demoboard TPS543C20AEVM

TPS543C20AEVM-054 40-A Single Phase Synchronous Step-Down Converter

Overview

TopologyBuck Converter
Input voltage5-16 V
Switching frequency500-20000 kHz
Output 10.9 V / 40 A

Description

The TPS543C20A uses an internally compensated emulated peak-current-mode control, with a clock synchronizable, fixed-frequency modulator for EMI-sensitive POL. The internal integrator and directly amplifying ramp tracking loop eliminate the need for external compensation over a wide range of frequencies thereby making the system design flexible, dense, and simple. Optional API and body braking help improve transient performance by significantly reducing undershoot and overshoot, respectively. Integrated NexFET™ MOSFETs with low-loss switching facilitate high efficiency and deliver up to 40 A in a 5-mm × 7-mm PowerStack™ package with a layout friendly thermal pad. Two TPS543C20A devices can be stacked together to provide up to 80-A point-of-load.
