Description
The AM101-73 is a low cost, switched capacitor voltage
converter. This CMOS based converter operates at a
relatively high frequency, permitting the use of low cost
ceramic capacitors. At supply voltages up to 3.1 V, the
inverted output follows the input voltage, and from
3.1–5.5 V, the output regulates to -3.1 V. Applications
include voltage conversion for FET/PHEMT power
amplifier control circuits, FET/PHEMT switch control, and
various other portable, mobile and wireless systems
