ISL62875 Features

* of both fixed-frequency and hysteretic PWM control. The PWM frequency is 500kHz during static operation, becoming variable during changes in load, setpoint voltage, and input voltage when changing between battery and AC-adapter power. The modulators ability to change the PWM switching frequency duri
