MicroPower inverter

Linear Technology’s LT3483 is a 40V, 200mA inverting DC/DC converter with an on-chip schottky diode in a ThinSOT package.

The LT3483 uses a current limited, fixed off-time architecture, which delivers high efficiency over a broad range of load current, while BurstMode operation allows quiescent current of only 40µA.

The LT3483’s input voltage range of 2.5V to 16V makes it suitable for single cell Li-Ion or multi-cell NiMH/NiCd and alkaline applications, as well as more general purpose fixed rail systems.

Its output voltage capability also make it ideal for a wide array of negative biasing applications, including CCD, LCD and general purpose negative voltage supplies.

The LT3483 can deliver up to 70mA at -5V from a 5V input. Additional features include an integrated feedback resistor output short-circuit protection. Its small package, high level of integration and use of tiny surface mount components yield a solution footprint of less than 40mm squared.

The LT3483 is available in a ThinSOT package from stock. Pricing starts at $2.05 each for 1,000-piece quantities.
