UPC1909 Description
DATA SHEET Bipolar Analog Integrated Circuit µPC1909 SWITCHING REGULATOR CONTROL IC The µPC1909 is a switching regulator control IC ideal for primary side control of active-clamp type Note DC/DC converters. This IC has 2 outputs employing a totem-pole circuit with peak output current 1.2 A, and is capable of directly driving a power MOS-FET. As a result, it has been possible to realize primary side control of an...
