1 / 15 page www.fairchildsemi.com REV. 1.0.2 7/6/00 Features • Provides complete, low-cost core and I/O power in single chip • I/O power sequencing • Core voltage adjustable from 1.5V to 3.6V • Independent adjustable current limits • Core up to 13A, I/O up to 5A • Precision trimmed low TC voltage reference • Constant On-Time oscillator • Small footprint 16 lead SOIC package Applications • High efficiency low-cost power for DSPs • Power for ASICs and FPGAs • Programmable dual power supply for high current loads Description The FAN5038 provides a complete low-cost power system for DSPs and other loads requiring high-performance. The FAN5038 combines an adjustable switch-mode DC-DC converter for core power with a low-dropout linear regulator for I/O power in a space-saving SO-16 package. Simple external circuitry provides power sequencing and indepen- dent current limits. An internal precision voltage reference allows the switcher to be adjusted from 1.5V to 3.6V. With the appropriate external components, the FAN5038 can deliver core power up to 13A, and I/O power up to 5A, allowing multiple DSPs to be powered with a single device.
