S1F75300 Series Step-up Switching Regulator With
Built-in Voltage Follower
DESCRIPTION
S1F75300 is a highly efficient and low power consump-
tion step-up switching regulator with built-in voltage
follower developed by using CMOS silicon gate pro-
cessor. (For boosting, the external coil is used.)
The output voltage is adjustable with the 8-bit elec-
tronic volume.
This IC is optimum to power supply portions of me-
dium and small liquid crystal panels for which high effi-
ciency is requested.
