Product data sheet Rev. 1 — 26 May 2015 2 of 35 NXP Semiconductors SSL8516BT Greenchip PFC and flyback controller 2. Features and benefits 2.1 Distinctive features Integrated PFC and flyback controller Universal mains supply operation between 90 V (AC) to 305 V (AC) Fixed boost PFC with accurate maximum output voltage (NXP Semiconductors patented) High level of integration, results in cost-effective designs with very low external component counts Adjustable PFC switch off delay External PFC switch on and switch off override Accurate PFC switch on and switch off control (NXP Semiconductors patents: EP2566024A1, US20130057170, CN102969909 A) 2.2 Green features On-chip start-up current source Reduced IC supply current during burst mode Power-down functionality for very low standby power 2.3 PFC green features Valley/Zero-Voltage Switching (ZVS) for minimum switching losses (NXP Semiconductors patented) Frequency limitation reduces switching losses PFC switched off when a low-load is detected at the flyback output 2.4 Flyback green features Valley switching for minimum switching losses (NXP Semiconductors patented) Frequency reduction with adjustable minimum peak current at low-power operation maintains high-efficiency at low output power levels Burst mode operation at very low-power levels for high-efficiency operation 2.5 Protection features Safe restart mode for system fault conditions Continuous mode protection using demagnetization detection for both converters (NXP Semiconductors patented) UnderVoltage Protection (UVP) (foldback during overload) Accurate OverVoltage Protection (OVP) for both converters (adjustable for flyback converter) Mains voltage independent OverPower Protection (OPP) Open control loop protection for both converters. The open-loop protection on the flyback converter is safe restart OverTemperature Protection (OTP) Low and adjustable OverCurrent Protection (OCP) trip level for both converters |
