The ADP5090 optimizes efficient conversion of the harvested limited power down to the 15 µW to 1 mW range with best-in-class sub-µW operation losses. Programmable maximum power point tracking with harvester open circuit voltage sensing ensures that the most energy is extracted from the harvester. The 260 nA quiescent current used in deep sleep mode prolongs operation time with minimal loss in the absence of ambient energy. Integrated charge pump circuitry enables a cold start at 380 mV input voltage with no energy on the system node. In addition to efficient ultralow power conversion, ADP5090 provides the best system design flexibility with support of charging different energy storage through external resistor programmability. An optional backup cell battery can be connected to the ADP5090 that intelligently manages and prioritizes power paths with fully integrated power switches. ADP5090 is capable of stopping a switcher within 10 μs delay to proceed transmitting data via an RF transceiver without interference by switching noise.

It generates superior efficiency, particularly in ultralight load condition such as sub-1 mW compared with other dc-to-dc switches. For batterypowered applications where systems need to be always on but consuming current as low as ten microamps. Unlike traditional PSM (power saving mode), which still consumes tens of microamp quiescent current, ADP5310 has only 600 nA I/Q, which enables the efficient conversion of up to a tens of microamps load. ADP5310 EN1 From MCU Channel 1 Buck Regulator (800 mA) PWRGD To MCU PVIN1 Moreover, the ADP5310 is equipped with a selectable forced PWM mode that allows for low noise output voltage when powering an analog sensitive load. ADP5310 benefits battery-powered systems with an extended battery life and offers high efficiency in standby mode and active mode. The ADP5310 also mitigates noise interference with analog loads. – + – + 2 × LiMnO2 Max = 15 V Min = 2.7 V PVIN2 10 µF PGND1 Sync/ Mode SW2 PGND2 Power Amplifier 10 µF R1 4.7 µH R2 VOUT Control (By DAC Or GPIO Switch) 2.2 V~2.8 V at 2 µA 10 µF MCU (Always On) FB2 Channel 3 Load Switch VREG 3.6 V~4.6 V 4.7 µH at 400 mA FB1 Channel 2 Ultralow Power Buck Regulator (50 mA/ 300 mA) NC EN3 From MCU SW1 2.2 V~2.8 V at 15 mA VOUT3 1µF ADF70xx (Rx/Tx) AGND 1 µF Mode: High = Forced PWM Low = Forced Hysteresis ULP micro-PMU for smart metering RF module.
