ADP5090-1-EVALZ(#2): 3.5V @ 800mA, 0.8 ~ 3.3V in

Summary

The ADP5090 is an ultralow, power synchronous, dc-to-dc boost regulator in a compact 3 mm × 3 mm LFCSP_WQ package. The ADP5090 runs from input voltages of 0.38 V to 3.3 V and requires minimal external components to provide a high efficiency solution with an integrated power switch, a synchronous rectifier, and battery management.

The EVAL-ADP5090 evaluation board provides an easy way to evaluate the device. This user guide describes how to quickly set up the board and deliver up to 3.5 V maximum voltage to the SYS output using an external resistor divide. The internal switches turn on if the storage element voltage at the BAT pin is above the externally programmed SETSD voltage of 2.4 V. The PGOOD indicator toggles high when the SYS pin ramps up to 3 V.

Complete information about the ADP5090 is available in the corresponding data sheet. Consult the data sheet in conjunction with this user guide when using the evaluation board.
