The LTC 1502-3.3 is a quadrupler charge pump DC/DCconverter that produces a regulated 3.3V output from asingle alkaline cell input. It requires only five small externalcapacitors-no inductors are required. Low supply cur-rent (40µA typical, 5µA in shutdown) and minimal externalcomponents make the LTC1502-3.3 ideal for space andpower conscious single-cell applications. The total printedcircuit board area of the circuit shown below is less than0.125in2.
Forcing the C1/SHDN pin low through an external resis-tive pull-down puts the part into shutdown mode. Duringshutdown, the internal oscillator is stopped and the load isdisconnected from VIN. An internal pull-up current on theC1/SHDN pin forces the part back into normal operationonce the pull-down resistance is removed.
The LTC1502-3.3 is short-circuit protected and survivesan indefinite VOUT short to ground. The LTC1502-3.3 isavailable in 8-pin MSOP and SO packages.
