Booster frequency

Version 1
    Question: What is the booster frequency?

     

    Answer:

    The steady state frequency of the switcher varies with the load current and can range from 10Hz (no load in SLEEP mode) and 110KHz when delivering maximum current at VBAT=1.8V. The start up oscillator, which only runs when the part is first connected to a supply, runs at about 250KHz.
