Description
The UC3871 is a complete power supply control solution for backlit LCDs typically used in laptop and notebook computers, and portable instrumentation. These applications require an adjustable high voltage AC current source to drive a cold cathode fluorescent lamp (CCFL) and an adjustable low voltage DC supply to bias the LCD. The UC3871 provides all control functions for these two supplies and also incorporates protection and synchronization circuitry. A low power shut-down input places the entire circuit into a very low current standby mode to reduce battery drain in portable systems and eliminate the need for a low-drop series switch.
Features
Complete power supply control solution for backlit LCDs
Adjustable high voltage AC current source to drive a CCFL
Adjustable low voltage DC supply to bias the LCD
Protection and synchronization circuitry
Low power shut-down input
Applications
Laptop and notebook computers
Portable instrumentation
Other applications requiring an adjustable high voltage AC current source and an adjustable low voltage DC supply
