UM10468 NXP Semiconductors SSL2108X buck evaluation board 1. Introduction WARNING Lethal voltage and fire ignition hazard The non-insulated high voltages that are present when operating this product, constitute a risk of electric shock, personal injury, death and/or ignition of fire.
UM10468 NXP Semiconductors SSL2108X buck evaluation board 2. Safety warning This reference board is connected to a high AC voltage (up to 250 V). Avoid touching the demo board during operation. An isolated housing is obligatory when used in uncontrolled, non-laboratory environments. Galvanic isolation of the mains phase using a fixed or variable transformer (Variac) is always recommended.

UM10468 NXP Semiconductors SSL2108X buck evaluation board 5. Connection data The evaluation board operates from either: • SSL21081 and SSL21082: 100 V (AC) to 120 V (AC) mains supply voltage • SSL21083 and SSL21084: 230 V (AC) mains supply voltage The evaluation board is designed to work with an LED module with an operating voltage •...
UM10468 NXP Semiconductors SSL2108X buck evaluation board Jumper J10A is connected in series with the brownout capacitor C8. Removing this jumper sets the brownout protection trigger values to be reset to default value. Remark: Brownout protection is only available in the SSL21082 and SSL21084.
UM10468 NXP Semiconductors SSL2108X buck evaluation board 7.1 Active bypass An increased value for the inrush current resistor causes the board to operate with the most phase cut dimmers, but also lowers the efficiency. If a higher power factor is not required, but leading-edge dimmer compatibility and high efficiency are important, the active bypass option is available.
UM10468 NXP Semiconductors SSL2108X buck evaluation board 8. Negative Temperature Coefficient (NTC) function The NTC pin can act as a control for thermal protection, an input for disabling/enabling the light output using PWM dimming and a soft-start function. When using the NTC pin as a control for thermal protection, the pre-soldered NTC RT1 can be used.
