1. Introduction_________________________________________________
This design note refers to the 158 997 Power LEDs Slider Demo Board. With the LDHM MagI³C Power Module
the feasibility of the colored as well as the white ceramic Power LEDs can be demonstrated. To run this board,
the user can switch between two modes: the battery mode or via wireless power transfer. In the PCB, a
capacitive touch sensor enables the adjustment of the dimming level.
2. Features ____________________________________________________

3. Description / Manual _________________________________________
Battery Mode:
In order to choose the battery mode, slide the switch to the position “Bat.”. To experience the light intensity,
push the tact switch next to one of the LEDs on the board and hold it. Simultaneously tap on the touch control
panel on the surface of the PCB and the LED will light up. Sliding over this area controls the dimming function.
The touch signal is registered by a microcontroller (MCU), subsequently transformed to a PWM signal (15 steps
@ 4 kHz) and transmitted to the DIM Pin of the LED driver module. The LED driver controls the dimming level
of the LED. After 30 seconds the demo board will turn off automatically. To restart the demo board, tap on the
“touch me” area again.
Please Note: Move the slide switch to the WPC position to save energy and avoid an early emptying of the
battery.
WPC Mode:
Move the slide switch to the WPC position. Take a Qi compliant WPC transmitter and put the demo board
centered above it. The other functions are equal to the battery mode (“Bat.”).
