TPS62122EVM-586

EVALUATION BOARD, SYNC BUCK CONVERTER.

The TPS62122EVM-586 is an evaluation module for TPS62122, a high efficient synchronous step down DC to DC converter optimized for low power applications. It supports up to 75mA output current and allows the use of tiny external inductors and capacitors. With its advanced hysteretic control scheme the converter provides power save mode operation. At light loads the converter operates in PFM mode (pulse frequency modulation) and transitions automatically in PWM (pulse width modulation) mode at higher load currents. The power save mode maintains high efficiency over the entire load current range. The hysteretic control scheme is optimized for low output ripple voltage in PFM mode in order to reduce output noise to a minimum. It consumes only 10uA quiescent current from VIN in PFM mode operation.
