Abstract
Certain aspects of the present disclosure generally relate to methods and apparatus for switching between modes of a multi-mode power supply circuit. One example power supply circuit generally includes a switched-mode power supply (SMPS) circuit, a voltage regulator circuit having an input coupled to an output of the SMPS circuit, the voltage regulator circuit being configured to be selectively enabled, a first voltage divider selectively coupled to the output of the SMPS circuit and selectively coupled to an output of the voltage regulator circuit, and a second voltage divider coupled to the output of the voltage regulator circuit.
