Overview
The LED7706TR is an LED lighting driver IC manufactured by STMicroelectronics, designed for LCD panel backlighting. It integrates a high-efficiency monolithic boost converter and six controlled current generators. The device supports an input voltage range of 4.5 V to 36 V and delivers up to 36 V output voltage. Each of the six channels provides a maximum output current of 30 mA. The switching frequency is adjustable from 250 kHz to 1 MHz. It operates within a temperature range of -40°C to +150°C and is housed in a 24-VFQFPN package.
Feature Summary
- Integrates a high-efficiency monolithic boost converter with six independent constant current generators for driving LED arrays.
- Supports PWM dimming with a minimum duty cycle of 1% at 20 kHz and includes fault detection for open and shorted LEDs.
- Features internal protections including thermal shutdown, output over-voltage protection, and internal MOSFET over-current limiting.
Applications
- Backlighting for LCD panels
- High brightness white LED arrays
- Industrial LED lighting systems
Procurement Notes
Verify component authenticity through authorized STMicroelectronics distributors or certified partners. Confirm RoHS compliance status and moisture sensitivity level (MSL) prior to assembly. Ensure the 24-VFQFPN package matches the design footprint. Review the official datasheet for specific handling and soldering recommendations to maintain reliability.
Selection Notes
