FAN5038M
Dual Voltage Controller for DSP Power
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
DescriptionThe 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.
