Certain aspects of the present disclosure generally relate to a switch mode power supply (SMPS). The SMPS generally includes at least one switch, an inductive element coupled to the at least one switch, and control circuitry, the control circuitry being configured to control the at least one switch, during each switching cycle of a plurality switching cycles of the SMPS, to transfer charge from an input voltage (Vin) node of the SMPS to the inductive element during an on-time of the switching cycle and transfer the charge to an output voltage (Vout) node of the SMPS during an off-time of the switching cycle. The on-time may be set based on a duty ratio of the SMPS, the duty ratio representing a ratio between a voltage at the Vin node and a voltage at the Vout node, the on-time being fixed depending on the duty ratio of the SMPS.
