Abstract
The present invention discloses a circuit with ESD protection and high voltage conversion for a switching regulator. It mainly comprises a non-overlap circuit, a power P-type MOS device, a parasitic diode, a digital logic AND gate, a pair of resistance and capacitance, a power N-type MOS device, an ESD N-type MOS device, a Lx pin and an ESD protection cell. The present invention can effectively decrease the on-resistance of MOS device and then improve the circuit efficiency.
