Product Profile of PFC & LLC Off-Line Controller with Half Bridge Driver

Power Integrations offers PFC & LLC Off-Line Controller with Half Bridge Driver. Power Integrations supplies wide ranges of high-voltage, analog integrated circuits for use in ac to dc conversion. PFC & LLC Off-Line Controller with Half Bridge Driver supports a universal input, continuous-current mode topology that does not require a sinusoidal input reference. This variable frequency controller provides high efficiency by switching the power at zero voltage, eliminating most switching losses.

PFC & LLC Off-Line Controller with Half Bridge Driver has the following features:

• Proprietary continuous conduction mode PFC, high efficiency with low component costs

• Frequency and phase synchronized PFC and LLC for reduced noise and EMI

• Ripple current reduction in PFC output capacitor

• Edge collision avoidance technology reduces noise sensitivity

• High efficiency Zero Voltage Switching [ZVS] LLC

• Configurable, precise dead time control and frequency limits

• Prevents hard MOSFET switching and helps optimize design

• Comprehensive PFC and LLC fault handling and current limiting

• Highly integrated, eliminates external components

Application Area of PFC & LLC Off-Line Controller with Half Bridge Driver are:

• 32 to 60 inch LCD TV and monitor display power supplies

• 150 W to 500 W high efficiency off-line power supplies
