Description
The PT6470 Excalibur鈩?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 14 A of output current, yet are housed in a
low-profile, 12-pin, package that is almost half
the size of the previous generation of products.
The integral copper case construction requires
no heatsink, and offers the advantages of solder-
ability and a small footprint (0.64 in虜 for suffix
鈥楴鈥?. Both through-hole and surface mount pin
configurations are available.
The PT6470 series operates from a 3.3-V
input to provide 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 1.0V DC.
Other features include external output voltage
adjustment, on/off inhibit, pre-bias startup, short
circuit protection, and an output remote sense.
