功能描述

The LTC1502-3.3 is a quadrupler charge pump DC/DC converter that produces a regulated 3.3V output from a single alkaline cell input. It requires only five small external capacitors-no inductors are required. Low supply current (40μA typical, 5μA in shutdown) and minimal external components make the LTC1502-3.3 ideal for space and power conscious single-cell applications. The total printed circuit board area of the circuit shown below is less than 0.125in2. Forcing the C1-/SHDN pin through an external resistive pull-down puts the part into shutdown mode. During shutdown, the internal oscillator is stopped and the load is disconnected from VIN. An internal pull-up current on the C1-/SHDN pin forces the part back into normal operation once the pull-down resistance is removed. The LTC1502-3.3 is short-circuit protected and survives an indefinite Vout short to ground. The LTC1502-3.3 is available in 8-pin MSOP and SO packages.
