All Rights Reserved. 4 EV4034-S-00B– UNIVERSAL INPUT, 3.5W, GU10 LED DRIVER CIRCUIT DESCRIPTION The EV4034-S-00B is configured for a singlestage, flyback topology. It uses primary-sidecontrol to simplify the schematic and reduce BOM costs. It can also achieve an accurate LED current. The input stage consists of FR1 and DB1. FR1 protects against component failure or some excessive short events, and can restrain the inrush current. CY1 is a Y capacitor that lowers common-mode noise to ensure a sufficient EMI margin. T1 is the power transformer, the structure of which is also very important to pass EMI test. D3, C5, and R7 compose output circuit. D3 is a Schottky diode for better efficiency. C5 is a ceramic capacitor for lower output-voltage ripple and R7 is the dummy load for open-lamp protection. The π filter (C1, L1, and C2) guarantees that the conducted EMI meets the EN55015 standard. The snubber circuit (R2, R3, D1, and C3) reduces the drain-source voltage spike. R4, C4, and D2 provide the VCC power supply. The resistor divider (R5 and R6) provides openlamp protection by sampling the voltage on the primary auxiliary winding. When an open occurs, the output voltage remains constant. EV4034-S-00B Rev.1.1 www.MonolithicPower.com 5/1/2018 MPS Proprietary Information. Patent Protected.
