Module DC-DC 1-OUT 1.8V 18A 18-Pin SIP Module

The PT5803 Excalibur series of integratedswitching regulators (ISRs) combines outstandingpower density with a comprehensive list offeatures. They are an ideal choice for applicationswhere board space is a premium and performancecannot be compromised. These modules provide18A of output current, yet are housed in a lowprofile,18-pin package that is almost half thesize of the previous product generation. Theintegral copper case construction requires noheatsink, and offers the advantages of solderabilityand a small footprint (0.736 in² for suffix ‘N’).Both through-hole and surface mount pin configurationsare available.The PT5803 series operates from a 5-V inputbus and provides a convenient point-of-load powersource for the industry’s latest high-performanceDSPs and microprocessors. The series includesoutput voltage options as low as 1.0VDC.Other features include external output voltageadjustment, a ±5% margin control, on/off inhibit,short circuit protection, thermal shutdown, and adifferential remote sense.
