The TPS543C20 employs 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 TPS543C20 devices can be stacked together to provide
up to 80-A point-of-load.
