LT3461ES6#TRMPBF

LT3461 is a general-purpose fixed frequency current mode step-up DC/DC converter. This device features an integrated schottky and a low VCESAT switch allowing a small converter footprint and lower parts cost. This switches at 3MHz. These high switching frequencies enable the use of tiny, low cost and low-height capacitors and inductors. The constant switching frequency results in predictable output noise that is easy to filter, and the inductor-based topology ensures an input free from switching noise typically present with charge pump solutions. The high voltage switch is rated at 40V making the device ideal for boost converters up to 38V. Application includes digital cameras, CCD bias supply, XDSL power supply, TFT-LCD bias supply, local 5V or 12V supply, medical diagnostics equipment, and battery backup.
