Texas Instruments TPS611781

Beschreibung

The TPS61178x family is a 20-V synchronous Boostconverter with the gate driver built-in for loaddisconnect. The TPS61178x integrates two low onresistancepower FETs: A 16-mΩ switching FET anda 16-mΩ rectifier FET.The TPS61178x uses the fixed frequency peakcurrent mode control with the slope compensationintegrated. At the light load, the TPS61178 enters intothe auto PFM mode while TPS611781 is in the forcedPWM mode.The TPS61178x could isolate the output from inputside when shutdown. Once the output is shorted, itenters into the hiccup mode to lower the thermalstress and can recover automatically after the shortreleases. Additionally, the TPS61178x also has OVPand thermal protection to avoid the fault operation.The TPS61178x is in a 3.0-mm x 3.5-mm 13-pinVQFN package with enhanced thermal dissipation.
