Applications

* Automatic intelligent switching between PWM low-noise and PFM low-current mode offers improved system control. During full-power operation, a fixed-frequency 3 MHz (typ. ), PWM mode drives loads from ~70 mA to 600 mA max. Hysteretic PFM mode extends the battery life through reduction of the quiescen
