The PT5810 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 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 solderability and a small footprint (0.736 in² for suffix 'N'). Both through-hole and surface mount pin configurations 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.
