Avoid touching the demo board while it is connected to the mains voltage. An isolated housing is obligatory when used in uncontrolled, non-laboratory environments. Galvanic isolation of the mains phase using a variable transformer is always recommended. a. Isolated Fig 2. b.

Functional description 4.1 Input filtering Common-mode and differential mode π filters are implemented to reduce common-mode or differential mode noise originating from the high-frequency (HF) switching currents/voltages in the primary of the converter from returning to the mains. This noise must be kept to a minimum by: • Small primary current loop (C2 to pin 1 of T1, pin 3 of T1 to drain of external MOSFET Q5, ground return from sense resistors R1, R24, R26 to C2 ground) • Snubber components D3, R17, C8 closely parallel to pins 1 and 3 of T1 • Track length from pin 3 of T1 to drain of external MOSFET to be small in order to reduce capacitance to surroundings For this 18 W application, C2 must be chosen sufficiently large to act as a buffer for the HF current flowing in the primary but also small enough to maintain a high PF where a value of 330 nF for C2 is a good compromise. 4.2 PF adjustment The divider network consisting of R5, R6, R7, R9, R10, D4, C10 and C11 modulates the base of Q7 according to the rectified mains. Consequently, a modulating current set by R11 flows through R8 and the sense current through R1, R24 and R26 is also modulated. Depending on the divider resistor values, the HF current through the primary has a current with a rectified mains modulation resulting in a high PF. The PF can be increased/decreased by decreasing/increasing R5 and R6 and a compromise can be reached between PF and line regulation. 4.3 RCD clamp Leakage inductance of the transformer is in series with primary inductance and the drain of MOSFET Q5. This leakage inductance together with the parasitic capacitance across the drain source of Q5 causes HF ringing when Q5 switches off. If the leakage is not minimized the voltage at the drain reaches high voltages levels which can damage Q5 if voltage levels exceed the maximum allowable level. An RCD clamp (R17, C8 and D3) prevents the voltage on the drain of Q5 exceeding the maximum drain voltage when Q5 switches off. 4.4 Supply voltage The supply voltage of the SSL2109A is achieved using an auxiliary winding. As further advantages, the auxiliary winding provides, via a resistor R25 on its underwinding, both a simple solution for improved load regulation using R12 and open-circuit protection (OCP) via the NTC pin using R13. 4.4.1 Open circuit protection If no LED string is connected to the converter output, the voltage can quickly exceed the maximum rating of the output capacitors C3 and C7. The underwinding of the auxiliary is connected to resistor R25 to prevent this. The voltage across R25 decreases as the output voltage increases. Consequently, the voltage at the NTC pin decreases once the current through R13 exceeds the internal current of the NTC pin. When the NTC voltage drops below 0.35 V then the SSL2109A UM10692 User manual All information provided in this document is subject to legal disclaimers. Rev. 1 — 9 April 2013 © NXP B.V. 2013.

An external 18 V Zener diode is included at the VCC pin to prevent that the voltage exceeds 20 V at the VCC pin for this no LED string situation 4.4.2 Short circuit When the LED terminals are shorted, the SSL2109A defaults to its maximum demagnetization time of 36 µs. This prevents that the transformer current ramps up to an excessively large value while the input power is limited and the SSL2109A enters OPS protection (latched) mode. Remark: Do not try to short-circuit the LED output while the circuit is powered or without discharging C3. The short-circuit protection is intended for zero-hour short circuit protection (so a short circuit during first assembly before power is applied).

Use a protective shield over application and never touch the board when measuring or testing. Connections and testing: • Connect a 10-LED string load to the SSL2109ADB1105 together with power meters at both inputs and outputs. • Connect V mains (120 V (AC)/60 Hz) using an isolating transformer (initially set to 0 V) to the input connection points of the flyback converter. Alternatively, use an AC power supply with limited output current capability (for example 200 mA). • Increase V mains to 120 V (AC) and measure the different parameters as shown in Table 3. Table 3.
