LT8336 DC/DC Converter

Analog Devices' LT8336 40 V, 2.5 A, low IQ synchronous step-up Silent Switcher®

Image of Analog Devices' LT8336 DC/DC Converter ADI's LT8336 is a low IQ synchronous step-up DC/DC converter. It features Silent Switcher architecture and optional spread spectrum frequency modulation to minimize EMI emissions while delivering high efficiencies at high switching frequencies.

Demonstration circuit 2505A is a low IQ Silent Switcher synchronous boost converter featuring the LT8336. DC2505A is designed to convert an 8 V to 20 V source to 24 V output with up to 1.5A load current, depending on the input voltage. DC2505A operates at 2 MHz switching frequency.

Features

  • Pass-Thru™ mode minimizes VIN-to-VOUT voltage drop to improve efficiency while maintaining ultra-low quiescent current (IQ)
  • Low EMI Silent Switcher architecture with spread spectrum meets CISPR25 conducted and radiated emissions standard
  • 3 MHz switching frequency reduces component size
