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 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.
