ROHM Semiconductor 

DC / DC converter for LCDs

BP5319 / BP5319X

The BP5319 and BP5319X are DC / DC converters for supplying power to liquid crystal displays (LCDs) panels.

These modules supply a negative voltage from power supply of 5V. They are available in a single in-line package

as an upright (BP5319) or L-shaped lead (BP5319X) type.

Applications

LCD panels in copiers, facsimiles, personal computers, word processors, instruments, and other displays

Features

1) Accurate output voltage. (−24V±0.75V)

2) High conversion efficiency. (typically 75%)

3) The external resistor can change an output voltage.

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.
