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. TPS53314 is a D-CAP™ mode, 6-A synchronous switcher with integrated MOSFETs.
