# SP6134HVLED Evaluation Board Summary

## Description
️· Designed for evaluating the SP6134H as a driver for Luxeon 1W, 3W, and 5W LEDs.
️· Fully assembled and tested surface mount board with probe access points.
️· Ideal for 24V bus applications.
️· Features high efficiency, small 10-pin MSOP package, and 600kHz switching frequency.

## Operating Instructions

1. Powering Up:
- Connect 24V power supply to “VIN” and “GND” posts.
- Connect 1W/3W/5W Luxeon LED between “VOUT” and “VFB” posts.
- Configure J1 jumper (see section 2) for desired application.
2. Jumper Configuration (J1):
- No hat: 1W application.
- Hat on 1 & 2: 5W application.
- Hat on 2 & 3: 3W application.
3. Bias Resistor Selection:
- Sets operating current of the LED.
- Formula: Rb = Vfb / If (Vfb = 200mV)
- Values:
■ 1W: Rb = 0.56Ω
■ 5W: Rb = 0.28Ω
■ 3W: Rb = 0.2Ω
