Description
The PT5810 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
a full 20 A 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 in2 for suffix ‘N’).
Both through-hole and surface mount pin con-
figurations are available.
The PT5810 series operates from a 3.3-V input
bus to provide 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 1.0 VDC.
Other features include external output voltage
adjustment, a ±5 % margin control, on/off inhibit,
short circuit protection, thermal shutdown, and a
differential remote sense.
