MOTOROLA ANALOG IC DEVICE DATA
The MC33463 series are micropower step–up switching voltage
regulators, specifically designed for handheld and laptop applications, to
provide regulated output voltages using a minimum of external parts. A wide
choice of output voltages are available. These devices feature a very low
quiescent bias current of 4.0
μ
A typical.
The MC33463H–XXKT1 series features a highly accurate voltage
reference, an oscillator, a variable frequency modulation (VFM) controller, a
driver transistor (Lx), a comparator and feedback resistive divider.
The MC33463H–XXLT1 is identical to the MC33463H–XXKT1, except
that a drive pin (EXT) for an external transistor is provided.
Due to the low bias current specifications, these devices are ideally suited
for battery powered computer, consumer, and industrial equipment where an
extension of useful battery life is desirable.
MC33463 Series Features:
Low Quiescent Bias Current of 4.0
