Abstract
Certain aspects of the present disclosure generally relate to a boost converter. The boost converter generally includes an inductor coupled to a first node, a first switch coupled between the first node and a reference node for the boost converter, and a feedback control circuit. The feedback control circuit may include a first input coupled to the first node, a second input coupled to a terminal of the first switch, and an output coupled to a control input of the first switch. The feedback control circuit may include a first amplifier having a first input coupled to the first input of the feedback control circuit and a second input coupled to a first reference voltage source. The feedback control circuit may also include a second amplifier having a first input coupled to a second reference voltage source and an output coupled to a power supply node of the first amplifier.
