Abstract
A switched mode power supply (SMPS) to output a smoothly rising voltage (V) during startup and still operate efficiently during steady state. A smoothly rising Vthat avoids a negative voltage slope and voltage overshoot may be desirable in some applications. The techniques of this disclosure include an adaptive loading time controlled oscillator (TCO) compensation circuit that adjusts the TCO frequency to linearly regulate the feedback voltage from the half-bridge (V). The TCO compensation circuit adapts to the startup loading and self-adjusts the regulation speed for the handover point between the TCO and the voltage controlled oscillator (VCO).
