Abstract
A switching power controller circuit comprises a first terminal pin for a high potential of a power supply for the controller circuit, a second terminal pin for providing output of switch drive signals and for receiving feedback signals, and a third terminal pin for receiving external current signals and for a low potential of the power supply. The switching power controller further comprises a clock generator, a pulse width modulation (PWM) generator, a reference generator, a power switch driver, a feedback signal sampler, a PWM comparator and a floating sampler.
