Booster frequency

Last Updated: December 28, 2011

What is the booster frequency?


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.
