Description
The PT5800 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 18A of output current, yet are housed in a lowprofile, 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 PT5800 series operates from a 5-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 inhibit, short circuit protection, thermal shutdown, and a differential remote sense.
