Safety warning The demo board input is connected to the 90 V to 265 V (AC) mains. Avoid touching the board while it is connected to the mains voltage and when it is in operation. An isolated housing is obligatory when used in uncontrolled, non-laboratory environments. Galvanic isolation from the mains phase using a fixed or variable transformer is always recommended. Figure 1 shows the symbols on how to recognize these devices. 019aab174 019aab173 a. Isolated Fig 1. UM10796 User manual b.

Board connections The SSL5031CDB1210 demo board is optimized for a 90 V to 265 V (AC) mains supply. It is designed to work with multiple LEDs or an LED module. Under the expected conditions, the output current is 300 mA when using an LED string with a forward voltage (VF) from 35 V to 60 V. The current can be adjusted using resistors R1 and R2. J1 and J2 are the connections for the mains voltage. J3 (LED+) and J4 (LED) are the connections for the LED load. Figure 4 shows the connections. Fig 4.

Functional description 6.1 Input filtering Capacitors C1 and C2 and inductor L1 filter the switching current from the buck converter to the line. Capacitors C1 and C2 also provide a low-impedance path for the switching current. To retain a power factor > 0.9, the value of capacitors C1 and C2 must be kept low. Varistor MOV1 across the AC line and the Transient Voltage Suppressor (TVS) diode on Vbus provide protection against transient surge voltages. 6.2 Setting the output current The LED output current is the primary parameter to set in an LED driver. It is regulated and sensed using Rsense resistors R1 and R2. The LED output current can be calculated with Equation 1: V reg  AV ISNS I LED = ----------------------------R sense (1) Where: • Vreg(AV)ISNS = 0.4 V V ISNS  max  Remark: I peak  max  = ------------------------- determines the maximum peak. R sense 6.3 Output OverVoltage Protection (OVP) Output OVP is implemented by measuring the voltage at the DEMOVP pin during the secondary stroke. The DEMOVP pin senses the output voltage through resistive divider (R5, R6, and R7) connected between the LEDP node and the DEMOVP pin. When it reaches V(th)ovp in an open-load condition, OVP is triggered and IC restarts when the VCC voltage is discharged internally. To prevent false OVP detection, an internal counter ensures that the OVP level is reached in three continuous cycles, triggering the OVP protection. So, to dissipate the energy from those three cycles during every restart, an output resistor (R8) is required. Remark: In SSL5031BTS version, DEMOVP pin is also used for thermal foldback protection. For more information, see the SSL5031BTS data sheet. UM10796 User manual All information provided in this document is subject to legal disclaimers.
