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
