LT1946A 2.7MHz Boost DC/DC Converter with 1.5A Switch and Soft-Start FEATURES s s s s s s s DESCRIPTIO 1.5A, 36V Internal Switch 2.7MHz Switching Frequency Integrated Soft-Start Function Adjustable Output from VIN to 35V Low VCESAT Switch: 300mV at 1.5A (Typical) 12V at 430mA from a 5V Input Small Thermally Enhanced 8-Lead MSOP Package U APPLICATIO S s s s s TFT-LCD Bias Supplies GPS Receivers DSL Modems Local Power Supply The LT®1946A is a fixed frequency step-up DC/DC converter containing an internal 1.5A, 36V switch. Capable of generating 12V at 430mA from a 5V input, the LT1946A is ideal for powering large TFT-LCD panels. The LT1946A switches at 2.7MHz, allowing the use of tiny, low profile inductors and low value ceramic capacitors.
