XC9504

Series

NOTE:

*1 Although the IC's step-up switching operations start from a VDD of 0.8V, the output voltage and oscillation frequency are

stabilized at VDD

≧2.0V. Therefore, a VDD of more than 2.0V is recommended when VDD is supplied from VIN or other

power sources.

*2 Although the IC's operations start from a VIN of 0.9V, the IC's power supply pin (VDD) and output voltage monitor pin (FB1)

should be connected to VOUT1.

With operations from VIN=0.9V, the 2nd channel's (output 2) EN2 pin should be disabled.

Once output voltage VOUT1 is more than 2.0V, the EN2 pin should be enabled.

*3 Please be careful not to exceed the breakdown voltage level of the peripheral parts.

*4 EFFI={ [ (output voltage) x (output current) ] / [ (input voltage) x (input current) ] } x 100
