Overview: Product Folder Order Now Technical Documents Tools & Software Support & Community TPS543B20 SLUSCR1B – MAY 2017 – REVISED MARCH 2018 TPS543B20 4-VIN to 19-VIN, 25-A Stackable, Synchronous Step-Down SWIFT™ Converter With.

General Description

The TPS543B20 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.
