Description
The S32A is a full-featured, 32-amp DC-DC converter that provides the
space-saving advantages of a Dual-in-line Packaging (DIP) form factor.
Ideal for powering todayís ASICs, DSPs and microprocessors, the S32A
features superb dynamic response, remote sense and overcurrent
protection. The programmable output allows the customer to standardize
on a single part for any output from 1.25 to 3.5 volts. Using a standard pin-
out, the S32A packs over 100 watts of power into a minimal 1.5 in2 of
board space.
