LT1946A - 2.7MHz Boost DC/DC Converter with 1.5A Switch and Soft-Start
LT1946A - 2.7MHz Boost DC/DC Converter with 1.5A Switch and Soft-Start - Linear Technology（凌力尔特）
The LT®1946A is a fixed frequency step-up DC/DC convertercontaining an internal 1.5A, 36V switch. Capable ofgenerating 12V at 430mA from a 5V input, the LT1946A isideal for powering large TFT-LCD panels. The LT1946Aswitches at 2.7MHz, allowing the use of tiny, low profileinductors and low value ceramic capacitors. Loop compensationcan be either internal or external, giving the userflexibility in setting loop compensation and allowing optimizedtransient response with low ESR ceramic outputcapacitors. Soft-start is controlled with an external capacitorwhich determines the input current ramp rate duringstart up. The 8-lead MSOP package and high switchingfrequency ensure a low profile overall solution less than1.1mm high.
