Internally-Compensated Advanced Current Mode Control 40-A POL Input Voltage Range: 16 V Output Voltage Range: 5.5 V Integrated 3/0.9-m Stacked NexFETTM Power Stage With Lossless Low-Side Current Sensing Fixed Frequency - Synchronization to an External Clock and/or Sync Out Pin Strapping Programmable Switching Frequency ­ 300 kHz to 2 MHz for Standalone ­ 300 kHz to 1 Mhz for Stackable Stack 2X for 80 A With Current Share, Voltage Share, and CLK Sync Pin Strapping Programmable Reference from 1.1 V With 0.5% Accuracy Differential Remote Sensing Safe Start-Up into Pre-Biased Output High-Accuracy Hiccup Current Limit Asynchronous Pulse Injection (API) and Body Braking × 7-mm LQFN Package with 0.5mm Pitch and Single Thermal Pad Create a Custom Design Using the TPS543C20 With the WEBENCH® Power Designer

The TPS543C20 employs an internally compensated emulated peak-current-mode control, with a clock synchronizable, fixed-frequency modulator for EMIsensitive 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 NexFETTM MOSFETs with low-loss switching facilitate high efficiency and deliver × 7-mm PowerStackTM package with a layout friendly thermal pad. Two TPS543C20 devices can be stacked together to provide to 80A point-of-load. Device Information(1)
