The ADP5091/ADP5092 is a 2-channel ultralow power energy harvesting PMU in a compact 4 mm × 4 mm LFCSP package. The ADP5091-1-EVALZ and ADP5092-1-EVALZ run from input voltages of 0.38 V to 3.3 V and require minimal external components to provide a high efficiency solution with integrated power switches, synchronous rectifier, battery management, and hybrid controlled and regulated output.
The ADP5091-1-EVALZ and ADP5092-1-EVALZ evaluation boards provide an easy way to evaluate the device. This user guide describes how to quickly set up the evaluation board and deliver up to 3.5 V maximum voltage to the SYS output using an external resistor divide. The internal switches turn on as long as the storage element voltage at BAT pin is above the externally programmed SETSD of 2.4 V. The PGOOD indicator toggles high when SYS ramps up to 3 V. The REG_OUT is set to 2.5 V as the default output voltage. Complete information about the ADP5091/ADP5092 is available in the ADP5091/ADP5092 data sheet. Consult the data sheet in conjunction with this user guide when using the evaluation boards.
