Description
The PT5820 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 16A of output current, yet are housed in a
low-profile, 18-pin, package. The integral copper
case construction requires no heatsink, and offers
the advantages of solderability and a small foot-
print (0.736 in2 for suffix ‘N’). Both through-hole
and surface mount pin configurations are available.
The PT5820 series operates from a 12-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 enable,
short circuit protection, and thermal shutdown. A
560-μF input capacitor and 330μF output capacitor
are required for proper operation.
