MC33468 Features

* a quiescent bias current of 3.0 µA typical. The MC33468 features a highly accurate voltage reference, an error amplifier, an oscillator, a variable frequency modulation (VFM) controller, a drive pin (EXT) for an external transistor, and feedback resistors. The Vout pin is fixed at 2V in the IC. The
