Typical Application Circuit for LT3461AES6 3.3V to ±5V Dual Output Converter. The LT3461A is a general purpose fixed frequency current mode step-up DC/DC converter. Both devices feature an integrated Schottky and a low VCESAT switch allowing a small converter footprint and lower parts cost. The LT3461A 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
