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.

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.

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