Description
The PT5800 Excalibur series of integrated
switching regulators (ISRs) combines outstand-
ing power density with a comprehensive list of
features. They are an ideal choice for applications
where board space is a premium and performance
cannot be compromised. These modules provide
18A of output current, yet are housed in a low-
profile, 18-pin package that is almost half the
size of the previous product generation. The
integral copper case construction requires no
heatsink, and offers the advantages of solderabil-
ity and a small footprint (0.736 in for suffix ‘N’).
Both through-hole and surface mount pin con-
figurations are available.
The PT5800 series operates from a 5-V input
bus and provides a convenient point-of-load power
source for the industry’s latest high-performance
DSPs and microprocessors. The series includes
output voltage options as low as 1.0VDC.
Other features include external output voltage
adjustment, a ±5% margin control, on/off inhibit,
short circuit protection, thermal shutdown, and a
differential remote sense.
