LT3464ETS8#TRPBF

LT3464 is a micropower step-up DC/DC converter with integrated Schottky diode and output disconnect. This device has a typical current limit of 115mA as well as fast switching speed to allow the use of a chip inductor and small ceramic capacitors. The internal PNP disconnects the output load from the input during shutdown, and also provides output short-circuit protection. An auxiliary reference input allows the user to override the internal 1.25V feedback reference with any lower value, allowing full control of the output voltage during operation. This device features a low 25µA quiescent current, which is further reduced to less than 0.5µA in shutdown. A current limited fixed off-time control scheme conserves operating current, resulting in high efficiency over a broad range of operating current. It is used in application such as OEL panel bias, LCD bias, handheld computers, battery backup, digital cameras, cellular phones etc.
