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.
FEATURE
• Availability of two outputs ; just inverted and twice inverted output
• Capability of output current ------- 30mA (min)
• Low voltage operation ------- Vin = 3V (typ)
• Low stand-by current (standby mode)
• Low out ripple (double clocking mode)
• Small 10-pin package
APPLICATION
• MMICs for a handy telephone and a PHS
