SC600AIMSTRT

Overview

The SC600AIMSTRT is a fractional charge pump LED driver IC from Semtech's mAhXLife series, designed for battery-operated applications. It operates within an input voltage range of 2.5 V to 6.5 V and provides a regulated constant current output of 60 mA at a fixed 5.0 V output level. The device utilizes a switching frequency of 650 kHz and is housed in a compact 10-lead MSOP package. It supports operation across a temperature range of -40°C to +85°C.

Feature Summary

• Fractional charge pump implementation eliminates the need for inductors, reducing electromagnetic interference and component count.
• Integrated short-circuit and over-temperature protection mechanisms ensure robust operation under fault conditions.
• Patented low noise mode switching circuitry allows for the use of extremely small input and output capacitors.

Applications

• LED backlighting for cellular phones
• Power supplies for PDAs and handheld computers
• Portable electronics and electronic books

Procurement Notes
