Product Details

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 integrated power switch, synchronous rectifier, and battery management.

The 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 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.
