VARIABLE FREQUENCY MICROPOWER DC-to-DC CONVERTER
Order this document by MC33468/D- -
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 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 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 μA High Output Voltage Accuracy of ±2.5% Low Startup Voltage of 0.8 V at No Load Output Voltage Set With External Resistors Operating Temperature Range: –40°C to +85°C Surface Mount Package
