TPS61178x Integrated Synchronous Boost Converters

Texas Instruments TPS61178x Integrated Synchronous Boost Converters have a built-in gate driver for load disconnect. Each device integrates two low on-resistance power FETs: A 16mΩ switching FET and a 16mΩ rectifier FET. The TPS61178x uses the fixed frequency peak current mode control with the slope compensation integrated. The TPS61178 enters the auto PFM mode at the light load, while the TPS611781 is in forced PWM mode. The TPS61178x could isolate the output from the input side when shut down. Once the output is shorted, it enters into the hiccup mode to lower the thermal stress and can recover automatically after the short releases. The Texas Instruments TPS61178x also has OVP and thermal protection to avoid fault operation.
