Abstract
Certain aspects of the present disclosure generally relate to soft starting a switched-mode power supply (SMPS) circuit operating as a charge pump in a reverse multiply-by-two mode. One example SMPS circuit generally includes a plurality of transistors, a capacitive element coupled to the plurality of transistors, and a current sink coupled between the capacitive element and a reference potential node for the SMPS circuit. For certain aspects, the current sink is configured to be enabled during a first phase of a soft start operation for the SMPS circuit, but is configured to be disabled during a second phase of the soft start operation and during normal operation for the SMPS circuit.
