ANALOG DEVICES LT3580IMS8E#PBF DC-DC Switching Boost Regulator, Adjustable, 2.5 to 32 V in, 42V/2A out, MSOP-EP-8

LT3580 is a PWM DC/DC converter containing an internal 2A, 42V switch. The LT3580 can be configured as either a boost, SEPIC or inverting converter. Capable of generating 12V at 550mA or �12V at 350mA from a 5V input, the LT3580 is ideal for many local power supply designs. The LT3580 has an adjustable oscillator, set by a resistor from the RT pin to ground. Additionally, the LT3580 can be synchronized to an external clock. The free running or synchronized switching frequency range of the part can be set between 200kHz and 2.5MHz. The LT3580 also features innovative active low SHDN pin circuitry that allows for slowly varying input signals and an adjustable under voltage lockout function. Typical applications include VFD Bias Supplies, TFT-LCD Bias Supplies, GPS Receivers, DSL Modems and Local Power Supply.
