Abstract
A switching mode power converter includes a DSC with a digital PWM module configured for complementary operation mode during normal operation. The control algorithm of the DSC is configured such that during an initialization stage immediately following power up of the device relevant digital PWM modules used for interleaving operation are reconfigured to temporarily operate in an independent operation mode with the duty cycle associated with each channel set at zero. The reconfigured digital PWM modules remain set in the independent operation mode for a predefined period of time. Once the predefined time period is reached, the reconfigured digital PWM modules are again reconfigured back to the original complementary operation mode configuration and the control algorithm resumes normal operation of the DSC and digital PWM modules.
