Description
The PT6470 Excalibur™ 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 generation of products. The integral copper case construction requires no heatsink, and offers the advantages of solderability and a small footprint (0.64 in² for suffix ‘N’). 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’s 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 outp...
