Product Details

The EVAL-ADPL21501-AZ evaluation board features the ADPL21501, a micropower step-up DC/DC converter in a ThinSOT™ package.

The ADPL21501 is designed for higher power systems with a 100mA current limit. A current-limited, fixed off-time control scheme conserves operating current, resulting in high efficiency over a broad range of load current.

The ADPL21501’s low off-time of 400ns permits the use of tiny, low-profile inductors and capacitors to minimize footprint and cost in space-conscious portable applications.

The EVAL-ADPL21501-AZ evaluation board features an application circuit with a 30V output voltage, operating within an input voltage range of 1V to 6V and a load current of 500μA.

The ADPL21501 data sheet must be read in conjunction with this user guide to properly use or modify the evaluation board.
