SLVS847A – NOVEMBER 2008 – REVISED DECEMBER 2016 TPS54917 3-V to 4-V Input, 9-A, Small Synchronous Buck
Switcher With Integrated FETs (SWIFTв„ў)
1 Features 3 Description As a member of the SWIFTв„ў family of DC-DC
regulators, the TPS54917 low-input voltage highoutput current synchronous buck PWM converter
offers the same features as the TPS54910 in a
smaller package and higher switching frequency,
which allows for a smaller total solution. Included on
the substrate with the listed features are a true, high
performance, voltage error amplifier that enables
maximum performance under transient conditions
and flexibility in choosing the output filter L and C
components; an undervoltage lockout (UVLO) circuit
to prevent start-up until the input voltage reaches 3 V;
an internally and externally set slow-start circuit to
limit in-rush currents; and a power good output useful
for processor or logic reset, fault signaling, and
supply sequencing. 1 13-mО© MOSFET Switches for High Efficiency at …
