A kind of soft-start circuit without overshoot suitable for power management module of high-speed response system was proposed. The clamp feedback circuit was used to realize stable switch without overshoot during the whole soft start process. Based on 0.25μm BCD technique(a kind of silicon processes combines the bipolar device, CMOS and DMOS for power and high-voltage elements), the circuit was verified by simulation. The simulation results show that the circuit can realize stable soft-start switch in a given temperature fluctuation range (–40–+125℃).Combined with the analysis of the whole system simulation results, the performance of the circuit achieves the expected goal of stable soft-start, and the module can be implemented in lightning guard monitor system, which has a high demand of response speed.
