Product Description

The TPS53355DQPT is a Synchronous Switcher with integrated power MOSFETs. It is designed for ease of use, low external component count and space-conscious power systems. This device features 5/2mR integrated MOSFETs, accurate 1%, 0.6V reference and integrated boost switch. A sample of competitive features include 1.5 to 15V wide conversion input voltage range, very low external component count, D-CAP™ mode control for super fast transient, auto-skip mode operation, internal soft-start control, selectable frequency and no need for compensation. The conversion input voltage ranges from 1.5 to 15V, the supply voltage range is from 4.5 to 25V and the output voltage range is from 0.6 to 5.5V.
Supports single rail input
Auto-skip Eco-mode™ for light-load efficiency
D-CAP™ mode with fast transient response
Integrated boost switch
Precharged startup capability
Adjustable overcurrent limit with thermal compensation
Overvoltage, undervoltage, UVLO and over-temperature protection
Supports all ceramic output capacitors
Open-drain power good indication
Incorporates NexFET™ power block technology
96% Maximum efficiency
