SSL4120中文资料Resonant power supply controller IC with PFC for LED lighting数据手册恩XP规格书

描述 Description

General description
The SSL4120 integrates a Power Factor Corrector (PFC) controller and a controller for a Half-Bridge resonant Converter (HBC) in a multi-chip IC. It provides the drive function for the discrete MOSFET in an up-converter and for the two discrete power MOSFETs in a resonant half-bridge configuration.Features and benefits
General features
■ Integrated PFC and HBC controllers
■ Universal mains supply operation from 85 V to 305 V (AC)
■ High level of integration resulting in a low external component count and a cost
   effective design
■ Enable input to enable only the PFC or both the PFC and HBC controllers
■ On-chip high-voltage start-up source
■ Stand-alone operation or IC supplied from external DC sourcePFC controller features
■ Boundary mode operation with on-time control
■ Valley/zero-voltage switching for minimum switching losses
■ Frequency limiting to reduce switching losses
■ Accurate boost voltage regulation
■ Burst mode switching with soft-start and soft-stopHBC controller features
■ Integrated high-voltage level shifter
■ Adjustable minimum and maximum frequency
■ Maximum 500 kHz half-bridge switching frequency
■ Adaptive non-overlap time
■ Burst mode switchingProtection features
■ Safe restart mode for system fault conditions
■ General latched protection input for output overvoltage protection or external
   temperature protection
■ Protection timer for time-out and restart
■ Overtemperature protection
■ Soft (re)start for both controllers
■ Undervoltage protection for mains (brownout), boost, IC supply and output voltage
■ Overcurrent regulation and protection for both controllers
■ Accurate overvoltage protection for the boost voltage
■ Capacitive mode protection for the HBC controller
