DS3992 Datasheet 2-channel Push Pull Ccfl Controller

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: .. Rev 0; 9/06 Two-Channel, Push-Pull CCFL Controller General.

General Description

The DS3992 is a low-cost, two-channel controller for cold-cathode fluorescent lamps (CCFLs) that are used to backlight liquid crystal displays (LCDs).

The DS3992 can drive multiple CCFLs per channel, making it ideal for 4- and 6-lamp LCD PC monitor and TV applications.

The DS3992 uses a push-pull drive scheme to convert a DC voltage (5V to 24V) to the high voltage (300VRMS to 1400VRMS) AC waveform that is required to power the CCFLs.

Key Features

  • o Two-Channel CCFL Controller for Backlighting LCD Panels for PC Monitors and LCD-TVs o Minimal BOM Provides Low-Cost Inverter Solution o Per-Channel Lamp Fault Monitoring for LampOpen, Lamp Overcurrent, Failure to Strike, and Overvoltage Conditions o Accurate (±10%) On-Board Oscillator for Lamp Frequency (40kHz to 80kHz) o Accurate (±10%) On-Board Oscillator for DPWM Burst-Dimming Frequency (90Hz to 220Hz or 180Hz to 440Hz) o Device Supply Undervoltage Lockout o Inverter Supply Undervoltage Loc.
