National Semiconductor LM2662/LM2663 Switched Capacitor Voltage Converter Datasheet
The LM2662 and LM2663 are CMOS charge‑pump voltage converters that invert or double an input voltage from 1.5 V to 5.5 V, delivering up to 200 mA of output current with high efficiency. They use two low‑cost external capacitors and offer selectable oscillator frequencies and a shutdown mode for ultra‑low quiescent current.
The document provides absolute maximum ratings, electrical characteristics, typical performance curves, application circuits, capacitor selection guidance, and physical dimensions for the SO‑8 package (LM2662M/LM2663M).
