ML9058E

6/76

*8:

VIN = 4.5 V, voltage multiplier capacitor C1 = 2.6 to 4.0 F, voltage multiplier output load current

I = 500

A. Only a voltage multiplier circuit operates, not activating the voltage adjustment circuit

and V/F circuit, by command “2C”.

*9:

V1 load current I = 400

A. 8 V is externally input to V

OUT.

The voltage adjustment circuit and V/F circuit operate by command “2B”. LCD output = no load

*10:

See Table 1 for the relationship between the oscillator frequency and the frame frequency.

Table 1. Relationship among the oscillator frequency (fOSC), external input frequency(fEXT)

display clock frequency (fLCDCK), and LCD frame frequency (fFR)
