Product Details

Description

The HiperLCS IC 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 (above) shows a simplified schematic of a HiperLCS based power stage where the LLC resonant inductor is integrated into the transformer.

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
    • Reduces assembly cost and reduces PCB layout loop areas
  • High maximum operating frequency of 1 MHz
    • Dramatically reduces magnetics size and allows use of SMD ceramic output capacitors
  • 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 and improved efficiency
  • Programmable burst mode maintains regulation at no-load and improves light load efficiency
  • Programmable soft-start time and delay before soft-start
  • Single package designed for high-power and high-frequency
    • Simple clip attachment to heat sink
    • Exposed thermal pad connected to ground potential – no insulators required between package and 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 amplifiers
