SP6682 is a high efficiency charge pump regulator ideal for driving white LEDs. It features low profile, inductorless regulator, X1.5 and X2 modes for highest efficiency, +2.7V to +5.5V input voltage range, fast turn-on time, 1mA quiescent current, <1.5µA shutdown current, built-in 600kHz oscillator, programmable output current or voltage, PWM dimming control with enable pin, shutdown to disconnect output from input, soft start to eliminate in-rush current, industry standard 10-pin MSOP package and small 10-pin DFN package.
The SP6682 is a current‑regulated charge‑pump IC designed to convert a Li‑ion battery voltage (2.7 V‑5.5 V) for driving white LEDs in back‑lit displays. It features an internal 600 kHz oscillator, automatic mode switching between X1.5 and X2 for optimal efficiency, programmable output current or voltage, PWM dimming via an EN/PWM pin, and a shutdown mode that draws less than 1.5 µA.
Typical applications include mobile phones, PDAs, digital cameras and MP3 players. The device is offered in 10‑pin MSOP and 10‑pin DFN packages, with ordering options for lead‑free and tape‑and‑reel formats. Detailed pin descriptions, electrical characteristics, performance graphs, and recommended low‑ESR capacitors are provided to aid PCB layout and design.
