Abstract:
The present invention relates to improving the reliability of the control IC of DC/DC converters. The present invention provides a control IC 200 of a rectifier diode-type buck DC/DC converter 100. An N-channel DMOS switch transistor M1 is disposed between an input terminal VCC and a switch terminal LX. A first diode D11 and an N-channel DMOS low-side transistor M2 are connected in series with and disposed between the switch terminal LX and a ground terminal GND.
