Features

Description

• 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

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.

• 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
