OR:
The SSL4101T combines a controller for Power Factor Correction (PFC)and a flyback controller. Its high level of integration allows the design of a cost-effective LED lighting application power supply with a very low number of external components. The built-in green functions provide high efficiency at all power levels. This applies to quasi-resonant operation at high power levels, quasi-resonant operation with valley skipping, as well as to reduced frequency operation at lower power levels. At low power levels, the PFC switches off to maintain high efficiency.
Features and benefits
- Integrated PFC and flyback controller
- True universal mains supply operation: 70 V (AC) to 305 V (AC)
- High level of integration, resulting in a:
- - very low external component count
- - cost-effective design
- On-chip start-up current source
- Valley/zero voltage switching for minimum switching losses
- Frequency limitation to reduce switching losses
- PFC is switched off when a low load is detected at the flyback output
- Valley switching for minimum switching losses
- Frequency reduction with fixed minimum peak current at low power operation
- Safe restart mode for system fault conditions
- Continuous mode protection by means of demagnetization detection
- UnderVoltage Protection (UVP) (foldback during overload)
- Accurate OverVoltage Protection (OVP) for both converters
- Open control loop protection for both converters
- IC overtemperature protection
- Low and adjustable OverCurrent Protection (OCP)
- General purpose input for latched protection
Applications
- Industrial high-bay and low-bay lighting
- Commercial interior lighting
- Parking garage and area lighting
- Street lighting
