Press Release Summary:
Available in 6-lead SOT-23 package, LT3483 utilizes current-limited, fixed off-time architecture and features BurstMode® operation for quiescent current of 40 µA. This 40 V, 200 mA inverting dc/dc converter has 2.5-16 V input voltage range and generates regulated negative outputs to -38 V. With footprint of less than 40 mm², product features integrated feedback resistor output short-circuit protection and uses surface-mount components.
Original Press Release:
MicroPower Inverter with Integrated Schottky in ThinSOT
Milpitas, CA - December 16, 2004 - Linear Technology Corporation announces the LT3483, a 40V, 200mA inverting DC/DC converter with an on-chip schottky diode in a ThinSOT(TM) package. The LT3483 utilizes 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 40uA. The LT3483's input voltage range of 2.5V to 16V makes it ideal 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 makes 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. The LT3483's small package, high level of integration and use of tiny surface mount components yield a solution footprint of less than 40mm2.
The LT3483 is available in a ThinSOT package from stock. Pricing starts at $2.05 each for 1,000-piece quantities.
