Quick Start Guide for Demonstration Circuit DC915: LT3466-1 WLED Driver and LCD Bias
High-efficiency WLED driver and LCD bias converter based on the LT3466-1, featuring dual outputs for 8 series LEDs and +/-15V bias with 3V to 14V input range.
Overview
The DC915 demonstration circuit features the LT3466-1, a high-efficiency white LED driver and step-up converter. It provides three outputs: VO1 for driving up to 8 series WLEDs at 15mA, and VO2/VO3 providing +/-15V at 10mA for LCD bias applications. The circuit operates from an input voltage of 3V to 14V. It includes jumpers for independent channel enabling and CTRL pins for PWM or analog dimming and voltage adjustment. The design features open-circuit protection (OVP) at 39.5V, a typical switching frequency of 800kHz, and an overall efficiency of 82% at a 3.6V input.
Use Cases
- White LED backlighting for handheld displays
