MOTOROLA ANALOG IC DEVICE DATA
The MC33466 series are micropower 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 15
μ
A typical.
The MC33466H–XXJT1 series features a highly accurate voltage
reference, an oscillator, a pulse width modulation (PWM) controller, a driver
transistor (Lx), an error amplifier and feedback resistive divider.
The MC33466H–XXLT1 is identical to the MC33466H–XXJT1, 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.
