ADP5091-1-EVALZ

The ADP5091-1-EVALZ is an evaluation board for ADP5091 ultra-low power energy harvesting PMU. The ADP5091 is a 2 channel, intelligent, integrated energy harvesting, ultralow power management unit (PMU) solution that converts DC power from PV cells or TEGs. This device charges storage elements such as rechargeable Li-Ion batteries, thin film batteries, super capacitors or conventional capacitors and power up small electronic devices and battery free systems. The evaluation board requires minimal external components to provide a high efficiency solution with integrated power switches, synchronous rectifier, battery management, hybrid controlled and regulated output. The ADP5091-1-EVALZ evaluation board provides an easy way to evaluate the device deliver up to 3.5V maximum voltage to 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 2.4V.

• Boost regulator with maximum power point tracking (MPPT) with dynamic sensing or no sensing mode
• Hysteresis mode for best ultralight load efficiency
• Optional BACK_UP power path management
• Input voltage range from 0.38V to 3.3V
• PGOOD indicator toggles high when SYS ramps up to 3V
• REG_OUT is set to 2.5V as the default output voltage
