TPS543B20 Step-Down SWIFT Converter

Texas Instruments TPS543B20 Step-Down SWIFT™ Converter employs an internally compensated emulated peak-current-mode control, with a clock synchronizable, a 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. This combination makes 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 25A in a 5mm × 7mm PowerStack™ package with a layout-friendly thermal pad.
