About this manual

The NCP1450A series are PWM step‑up DC‑DC switching controllers designed for portable equipment powered from one or two battery cells. The device integrates a PWM oscillator, controller, error amplifier, soft‑start, voltage reference and a driver for an external power transistor, requiring only six external components for a high‑efficiency converter.

Typical applications include PDAs, electronic games, portable audio, digital cameras and handheld instruments. The datasheet includes ordering information, pin descriptions, electrical characteristics, maximum ratings, and evaluation‑board details, along with package dimensions for the TSOP‑5 package.
