com Order this document by MC33468/D MC33468 Variable Frequency Micropower Step-up DC-DC Converter 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...
