The PW2052 is a high efficiency, high frequency synchronous DC-DC step-down regulator. The 100%
duty cycle feature provides low dropout operation, extending battery life in portable systems.
The internal synchronous switch increases efficiency and eliminates the need for external Schottky
diode. At shutdown mode, the input supply current is less than 1µA. The current limit protection and
on-chip thermal shutdown features provide protection against any combination of overload or
ambient temperature.
