DC / DC converter for LCDs
BP5302A / BP5302XA
The BP5302A and BP5302XA are DC / DC converters for supplying power to liquid crystal display (LCD) panels.
The modules supply a negative voltage from a positive power supply. They are available in a single in-line
package as an upright (BP5302A) or L-shaped lead (BP5302XA) type.
Applications
LCD panels in personal computers and word processors
Features
1) Wide input voltage range.(+5V to
+14V)
2) High accurate output voltage. (
鈭?4鹵0.75V)
3) High conversion efficiency. (Typ. 80%)
4) Built-in protection circuit.
5) Built-in ON/OFF switch.
6) Compact and light.
7) Available as an upright or L-shaped lead type.
