The LTC~1502-3.3 is a quadrupler charge pump DC/DC converter that produces a regulated 3.3V output from a single alkaline cell in p ut. It req uires only five small exte rnal capacitors-no inductors are required. Low supply cur- rent (40 typical, 5A 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.
