Evaluation Board for the ADP5090 Ultralow Power Boost Regulator
GENERAL DESCRIPTION
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.
