Description for the TPS543B20

The TPS543B20 employs an internally compensated emulatedpeak-current-mode control, with a clock synchronizable, fixed-frequency modulator for EMI-sensitivePOL. The internal integrator and directly amplifying ramp tracking loop eliminate the need forexternal 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 bysignificantly reducing undershoot and overshoot, respectively. Integrated NexFET™ MOSFETs with low-loss switching facilitate high efficiency anddeliver up to 25 A in a 5-mm × 7-mmPowerStack™ package with a layout friendly thermal pad. TwoTPS543B20 devices can be stacked together to provide up to50-A point-of-load.
