Flyback power supply controller IC with PFC for LED lighting

This device is no longer available. Please see the EOL notice.

Integrated PFC and flyback controller
Universal mains supply operation between 90 V (AC) to 305 V (AC)
High level of integration, results in cost-effective designs with very low external component counts
On-chip start-up current source
Power-down functionality for very low standby power
Valley/Zero-Voltage Switching (ZVS) for minimum switching losses
Frequency limitation reduces switching losses
PFC switched off when a low-load is detected at the flyback output
Valley/Zero-Voltage Switching (ZVS) for minimum switching losses
Frequency limitation reduces switching losses
PFC switched off when a low-load is detected at the flyback output
Valley switching for minimum switching losses
Frequency reduction with adjustable minimum peak current at low-power operation maintains high-efficiency at low output power levels
Safe restart mode for system fault conditions
UnderVoltage Protection (UVP)
Accurate OverVoltage Protection (OVP)
Mains voltage independent OverPower Protection (OPP)
Open control loop protection for both converters
OverTemperature Protection (OTP)
Low and adjustable OverCurrent Protection (OCP) trip level for both converters
General-purpose input for latched protection
