Description
The PT6460 Excalibur鈩?series of integrated
switching regulators (ISRs) combines outstanding
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 14 A
of output current, yet are housed in a low-profile,
12-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 solderability and a small footprint
(0.64 in虜 for suffix 鈥楴鈥?. Both through-hole and
surface mount pin configurations are available.
The PT6460 series operates from a 5-V input
bus and provides a convenient point-of-load power
source for the industry鈥檚 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, on/off inhibit, pre-bias startup, short
circuit protection, and an output remote sense.
