Analog Devices Inc. EVAL-ADPL21504-AZ Converter Evaluation Board
Analog Devices EVAL-ADPL21504-AZ Converter 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 enables the use of tiny, low-profile capacitors and inductors to minimize cost and footprint in space-conscious portable applications.
The Analog Devices 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 up to 20mA.
