Abstract
In one example, there is disclosed a hybrid analog-digital point-of-load controller (ADPOL) for use in a power supply. The ADPOL is configured to respond to transient current loads. In the presence of moderate current transients, power is clocked by a digital power core, which may be programmatically configured to adjust pulse width in response to the transient. In the presence of larger current transients, control may be passed to an analog transient compensator, which includes high-speed circuitry selecting between a very high-duty-cycle clock and a very low-duty-cycle clock, which will drive the transient back to the digital control domain.
