BP5307
The BP5307 is a DC / DC converter unit designed for driving liquid crystal displays (LCDs). The unit supplies a positive
voltage for LCDs from a logic circuit power supply ()5V). Being in a compact and light surface-mount package, the IC
can be built into a LCD panel.
FApplications
LCD panels of personal computers, word processors, and copiers
FFeatures
1) Automatic mounting and reflow soldering are pos-
sible.
2) With a maximum thickness of 4.1mm, the IC can be
built into a LCD panel.
3) Output voltage can be regulated by a microcontroller.
4) Discharg circuit is built in for output. (Fall time: 1ms
Typ.)
FAbsolute maximum ratings (Ta = 25_C)
