The TPS62120DCNT is a 96% Efficiency Step-down Converter with DCS-control optimized for low-power applications. The device 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 pulse frequency modulation (PFM) mode and transitions automatically in pulse width modulation (PWM) 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. The device consumes only 10µA quiescent current from VIN in PFM mode operation. In shutdown mode, the device is turned off. An open-drain power good output is available in the TPS62120 and indicates once the output voltage is in regulation.
