REFERENCE VOLTAGE GENERATOR FOR REDUCED VOLTAGE OVERSHOOT IN A SWITCH MODE REGULATOR AT THE END OF SOFT-START |
摘要 |
The reference voltage generator for a switch mode regulator includes: a reference voltage source; a soft-start voltage generator; and a comparator having a directional offset for comparing an output of the reference voltage source with an output of the soft-start voltage generator. Because of the intentional directional offset, the pass switch does not turn ON during the transition from the ramp voltage to reference voltage, therefore reducing energy stored in the inductor. Thus the voltage overshoot is reduced during the end of the soft-start cycle.
