HDLV S32A-5SDAC-RA Family 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 todayis 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 pinout, the S32A packs over 100 watts of power into a minimal 1.5 in2 of board space.
