TPS7H4003-SEP Overview
The TPS7H4003-SEP is a radiation-tolerant, 7-V, 18A synchronous buck converter with integrated lowresistance high-side and low-side MOSFETs in a thermally enhanced 34-pin ceramic flatpack package. High efficiency and reduced ponent count are achieved through current mode control. The output voltage start-up ramp is controlled by the SS/TR pin which allows operation as either a stand alone power supply or in tracking...
