Linear Technology / Analog Devices Inc. LT�86xx synchronous step-down regulators feature Silent Switcher� architecture designed to minimize EMI/EMC emissions while delivering high efficiency at frequencies up to 3MHz. Assembled in a 3mm � 4mm QFN package, the monolithic construction with integrated power switches and the inclusion of all necessary circuitry yields a solution with a minimal PCB footprint. An ultra-low 2.5�A quiescent current enables applications requiring highest efficiency at very small load currents. Transient response remains excellent and output voltage ripple is below 10mVP-P at any load, from zero to full current.

Feature

  • Silent Switcher® Architecture
    • Ultralow EMI Emissions
    • Spread Spectrum Frequency Modulation
  • High Efficiency at High Frequency
    • Up to 95% Efficiency at 1MHz, 12VIN to 5VOUT
    • Up to 94% Efficiency at 2MHz, 12VIN to 5VOUT
  • Wide Input Voltage Range: 3V to 65V
  • 3.5A Maximum Continuous Output, 5A Peak Transient Output
  • Ultralow Quiescent Current Burst Mode® Operation
    • 2.5μA IQ Regulating 12VIN to 3.3VOUT
    • Output Ripple < 10mVP-P
  • Fast Minimum Switch-On Time: 35ns
  • Low Dropout Under All Conditions: 130mV at 1A
  • Safely Tolerates Inductor Saturation in Overload
  • Adjustable and Synchronizable: 200kHz to 3MHz
  • Peak Current Mode Operation
  • Output Soft-Start and Tracking
  • Small 18-Lead 3mm × 4mm QFN
