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
