Description

The LT®3460 is a general purpose step-up DC/DC converter.
The LT3460 switches at 1.3MHz, allowing the use of tiny, low cost and low height capacitors and inductors.
The constant frequency results in low, predictable output noise that is easy to filter.

The high voltage switch in the LT3460 is rated at 38V, making the device ideal for boost converters up to 36V.
The LT3460 can generate 12V at up to 70mA from a 5V supply.

The LT3460 is available in SC70 and SOT-23 packages.
