Product Summary

The LX1910CLQ PWM buck regulator achieves very high efficiencies over a broad range of operating load conditions. The LX1910CLQ implements a load-detection architecture and enters a power-saving PFM mode when driving small load currents ensuring optimal regulator efficiency over the entire output current range thus maximizing battery life. The PWM operating mode implements a fixed frequency of 1MHz (typ), the transconductance error amplifier has 12μA of drive with an output voltage swing rail to rail. Compensation of LX1910CLQ is external for maximum user flexibility.
