DESCRIPTION
TPS53314 is a D-CAP™ mode, 6-A synchronous
switcher with integrated MOSFETs. It is designed for
ease of use, low external component count, and
small package power systems.
This device features single-rail input support, one
20-mΩ and one 7.5-mΩ integrated MOSFET,
accurate 1%, 0.6 V Reference, and integrated boost
switch. A sample of competitive features include:
greater than 96% maximum efficiency, 3 V to 15 V wide input voltage range, very low external
component count, D-CAP™ mode control for super
fast transient, selectable auto-skip and PWM
operation, internal soft-start control, adjustable
frequency, and no need for compensation.
The conversion input voltage ranges from 3 V to
15 V, the supply voltage range is from 4.5 V to 25 V,
and the output voltage range is from 0.6 V to 5.5 V.
The TPS53314 is available in a 5 mm × 7 mm 40-pin,
QFN package and is specified from –40°C to 85°C.
