The boost (step-up) converter is • Operating Voltage Range of 2.5V to 7V used to generate an adjustable output voltage and features a low RDSON internal switch for maximum • 660kHz/1.28MHz Pin Selectable Switching efficiency. The operating frequency is selectable Frequency between 660kHz and 1.28MHz allowing for the use of • Adjustable Soft-Start Function small external components. An external soft-start pin • Input Undervoltage Protection enables the user to tailor the soft-start time to a specific application and limit the inrush current. The • Over Temperature Protection Op-Amp is capable of sourcing/sinking 135mA of • Integrated Op-Amp current (typical). The gate pulse modulation switch • Integrated Gate Pulse Modulation (GPM) can operate with a VGH voltage of 5V to 30V. The Switch LM3310 is available in a low profile 24-lead WQFN package. • 24-Lead WQFN Package APPLICATIONS • TFT Bias Supplies • Portable Applications Typical Application Circuit 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
