Power supply circuit and method

An integrated power supply (106) is formed on a semiconductor substrate (200). A first switch (150) is formed in a well region (155) of the semiconductor substrate to have a conduction path (211) for coupling a supply voltage (VBAT) to a node (116). A second switch (152) operates in response to a fi...

Zusammenfassung:An integrated power supply (106) is formed on a semiconductor substrate (200). A first switch (150) is formed in a well region (155) of the semiconductor substrate to have a conduction path (211) for coupling a supply voltage (VBAT) to a node (116). A second switch (152) operates in response to a first control signal (COMP) for coupling the node to the well region when a potential of the node is greater than the supply voltage.
