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.
