BP5317

Regulator ICs Surface-mount power supply unit for LCD drivers BP5317 The BP5317 is a DC / DC converter unit designed for driving liquid crystal displays (LCDs). The unit supplies a positive voltage for LCDs from a logic circuit power supply ()5V). Being in a compact and light surface-mount package, the IC can be built into an LCD panel. FApplications LCD panels of personal computers, word processors, and copiers FFeatures 1) Automatic mounting and reflow soldering supported. 2) Compact size and thin design enable internal installation in LCD panels. 3) Internal short-circuit protection.
