Product Details

The EVAL-ADPL21504-AZ evaluation board features the ADPL21504, a micropower step-up DC/DC converter in a ThinSOT™ package.

The ADPL21504 is designed for higher power systems with a 350mA 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 ADPL21504’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-ADPL21504-AZ evaluation board features an application circuit with a 20V output voltage, operating within an input voltage range of 2.5V to 4.2V and a load current upto 20mA.

The ADPL21504 data sheet must be read in conjunction with this user guide to properly use or modify the evaluation board.
