EVAL-LT8334-AZ

Evaluation circuit EVAL-LT8334-AZ features LT®8334 in a SEPIC configuration. This evaluation circuit features Spread Spectrum Frequency Modulation (SSFM), EMI filters and space for an option EMI shield to provide optimum EMI performance. The evaluation board contains a selectable jumper, JP1, to aid in the selection of the desired SYNC pin mode of operation. At light load, either PULSE SKIP or low-ripple BURST mode can be selected to improve the efficiency. The LT8334 boost/SEPIC/inverting converter IC operates over an input range of 2.8V to 40V, suitable for automotive, telecom, and industrial applications. The LT8334 packs other popular features such as soft-start, bias pin, input undervoltage lockout. The IC can exhibit a low quiescent current down to 9μA in BURST mode and 1μA in shutdown, which makes it ideal for battery-operated systems. The LT8334 is assembled in a thermally enhanced 12-lead 4mm × 3mm DFN package.

• Typical efficiency (with EMI filters) of 87% (VIN = 16V, VOUT = 12V, IOUT = 2.2A)
• Operates with a switching frequency of 2MHz and designed to convert a 3V to 26V source to 12V output
• Converter can output up to 2.2A depending on the input voltage
• PCB layout is optimized for good EMI performance and small solution size
• Converter provides adjustable and synchronizable operation from 300kHz to 2MHz with SSFM option
