Features

• LLC half-bridge power stage incorporating controller, high and

low-side gate drives, and high-voltage power MOSFETs

• Eliminates up to 30 external components

• High maximum operating frequency of 1 MHz

• Nominal steady-state operation up to 500 kHz

• Dramatically reduces magnetics size and allows use of SMD

ceramic output capacitors

• Precise duty symmetry balances output rectifier current, improving

efficiency

• 50 ±0.3 typical at 300 kHz

• Comprehensive fault handling and current limiting

• Programmable brown-in/out thresholds and hysteresis

• Undervoltage (UV) and overvoltage (OV) protection

• Programmable over-current protection (OCP)

• Short-circuit protection (SCP)

• Over-temperature protection (OTP)

• Programmable dead-time for optimized design

• Programmable burst mode maintains regulation at no-load and

improves light load efficiency

• Programmable soft-start time and delay before soft-start

• Accurate programmable minimum and maximum frequency limits

• Single package designed for high-power and high-frequency

• Reduces assembly cost and reduces PCB layout loop areas

• Simple single clip attachment to heat sink

• Staggered pin arrangement for simple PC board routing and

high-voltage creepage requirements

• Paired with HiperPFS PFC product gives complete, high efficiency,

low part count PSU solutions
