TPS543C20 Step-Down SWIFT™ Converters

Texas Instruments TPS543C20 Step-Down SWIFT™ Converter 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. This feature makes the system Design flexible, dense, and simple. Optional API and Body Braking help improve transient performance by significantly reducing undershoot and overshoot. Integrated NexFET™ MOSFETs with low-loss switching facilitate high efficiency and deliver up to 40A in a 5mm x 7mm PowerStack™ package with a layout-friendly thermal pad. Two Texas Instruments TPS543C20 devices can be stacked to provide up to 80A point-of-load.
