NXP Semiconductors
SSL8516T
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 patent pending)
2.2 Green features
On-chip start-up current source
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
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
General-purpose input for latched protection, for use with system OverTemperature
Protection (OTP)
