The LX1910 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 is external for maximum user flexibility. The LX1910 does not require a minimum load current for stable operation.
