The TPS62A04B and TPS62A04AB are synchronous, step-down, buck, DC/DC converters designed for high efficiency and compact design size. The device uses integrated switches for constantly delivering an output current of 4A. The device operates in pulse width modulation (PWM) mode with 2.2MHz switching frequency at medium to high load. At light load, the TPS62A04B device variant automatically enters a power save mode (PSM) to maintain high efficiency over the entire load current range. The A variant of this device family (TPS62A04AB) stays PWM mode at all times irrespective of the load condition. The device maintains stable frequency and lowest ripple.

The TPS62A04B and TPS62A04AB use an external resistor divider to set the output voltage. The internal soft-start circuit limits the inrush current during start-up, and a power-good signal indicates correct output voltage. Overcurrent protection combined with thermal shutdown protect device and application. The devices are available in an SOT563 package.
