Product Details

The EVAL-ADPL26001-AZ evaluation board features ADPL26001, a low-IQ boost/SEPIC/inverting converter with a 1A, 60V switch.

The ADPL26001 allows higher input and output voltages than comparable converters and also significantly reduces input current at light loads and no load. The ADPL26001 regulates either positive or negative outputs and has an internally programmed switching frequency of 2MHz.

The EVAL-ADPL26001-AZ evaluation board consists of two circuits: one circuit is a boost converter with 48V output voltage operating from input voltage range of 10V to 36V. The second circuit is an inverting converter with -12V output voltage operating from input voltage range of 4V to 36V.

Low input current at light loads, a high voltage rating and negative output capability make the ADPL26001 attractive for battery-powered and extended voltage range regulator circuits. The ADPL26001 data sheet must be read in conjunction with this user guide to properly use or modify the EVAL-ADPL26001-AZ evaluation board.
