M62262FP
VOLTAGE CONVERTER FOR MMIC
GENERAL DESCRIPTION
The M62262FP is a CMOS voltage converter for driving MMICs. It includes a input inverter utilizing a charge-pump technique, therefore it can provide both a just inverted output (-Vo) and a twice inverted output (-2Vo) by connecting an external capacitor. It can also switch over between a stand-by mode (a halt function with low power dissipation) and a double clocking mode for reducing output ripples. PIN CONFIGURATION(TOP VIEW)
