The AAT1277IUT-T1 from Skyworks Solutions is a versatile step-up current regulator ideal for LED photo flash and torch applications in single-cell Li-ion powered products like cellphones and smartphones. This device features a high switching frequency of 2MHz, enabling the use of small inductors and capacitors, making it suitable for compact battery-powered devices.
It provides up to 1.5A of regulated output current, split between two channels (750mA per channel), and achieves up to 85% efficiency with a small 1μH inductor. The AAT1277IUT-T1 supports independent control for flash and movie modes, user-programmable safety timers, and includes protection features such as over-voltage, short-circuit, and over-temperature protection. The device operates within a 2.7V to 5.5V input voltage range and has a shutdown current of less than 1.0 μA.
Packaged in an 18-ball 1.5mm x 2.4mm CSP, this surface-mount component is designed for efficient integration into space-constrained designs. Its dual-channel output capability allows for driving one or two LEDs, matching current between diodes if two are used.
