MOTOROLA ANALOG IC DEVICE DATA
The MC33468 is a micropower step–up switching voltage regulator,
specifically designed for handheld and pager applications, to provide a
regulated output voltage using a minimum of external parts. This device
features a quiescent bias current of 3.0
μ
A 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 output of the converter with an
inductor, a diode, a capacitor, a drive transistor, and feed–back resistors can
have an output of 30V.
MC33468 Features:
Low Quiescent Bias Current of 3.0
μ
A
High Output Voltage Accuracy of
±
2.5%
Low Startup Voltage of 0.8 V at No Load
Output Voltage Set With External Resistors
