1 / 30 page  HiperLCS Family www.power.com May 2017 Integrated LLC Controller, High-Voltage Power MOSFETs and Drivers This Product is Covered by Patents and/or Pending Patent Applications. Product Highlights 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 Applications • High-efficiency power supplies (80 PLUS Silver, Gold and Platinum) • LCD TV power supplies • LED street and area lighting • Printer power supplies • Audio amplifier Description The HiperLCS™ is an integrated LLC power stage incorporating a multi-function controller, high-side and low-side gate drivers, plus two power MOSFETs in a half-bridge configuration. Figure 1 shows a simplified schematic of a HiperLCS based power stage where the LLC resonant inductor is integrated into the transformer. The variable frequency controller provides high-efficiency by switching the power MOSFETs at zero voltage (ZVS), eliminating switching losses. Figure 1.
