PT5820

The PT5820 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 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 footprint (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-F input capacitor and 330F output capacitor are required for proper operation.
