BP5319 / BP5319X
The BP5319, BP5319X is a DC/DC converter designed for driving liquid crystal displays(LCDs). If this module is used, a negative power supply for LCD can be made of the power supply easily 5V.
!Applications A power supply for the LCD panels in copiers, facsimile, personal computers, word processors, musical instrument, and units.
!Features 1) High accurate output
voltage (-24V±0.75V). 2) High conversion efficiency (75%Typ). 3) An output
voltage can be changed by the external resistor. 4) Built-in protect circuit. 5) Built-in ON/OFF switch. 6) Compact and light. 7) Available as an upright or L-shaped lead type.
