LTC3109EUF #PBF is a power management integrated circuit (PMIC) technology designed for an ultra-low power use case. It is a fully integrated PMIC with a low quiescent current and very low voltage dc-to-dc converter, DC-DC boost, and Li-ion battery charger for versatile energy harvesting scenarios. With on board integrated charge and voltage regulators, the LTC3109EUF #PBF packs all of the necessary power components into a single chip, thus reducing bill of materials costs and complexity of the design, while optimizing the overall power budget.

The LTC3109EUF #PBF PMIC offers a versatile range of power management functions in a single chip, enabling significant savings in board space and cost. It is suitable for powering low power microcontrollers and sensor nodes, as well as a variety of other applications requiring ultra-low power DC-DC converters and Li-ion battery chargers. Even with its low power consumption, the circuit is able to provide reliable and efficient energy harvesting in a wide range of operating conditions due to its low voltage operating range.

The functional block diagram of the LTC3109EUF #PBF PMIC shows its four main functional blocks; the DC-DC buck regulator, the DC-DC boost regulator, the battery charger block, and the 2 x 3 microcontroller interface. The buck regulator is a synchronous step-down converter with up to 5A or 2A current handling, and with adjustable output voltage from 0.8V to 1.8V. The boost regulator is a low noise, high-efficiency, synchronous step-up converter that is rated up to 2A current and with adjustable output voltages from 0.85V to 3.6V.

The charger block is a current-limiting Li-ion battery charger with adjustable charge current (0.1A to 1.25A) and charge voltage (2.9V to 4.3V). The charger block includes advanced safety features such as short circuit, reverse polarity, and thermal shut down options, allowing it to be safely used in a wide range of applications. The 2 x 3 microcontroller interface is a dual voltage, bidirectional controller interface, which supports 3.3V, 2.5V and 1.2V operation. The controller is rated up to 5A or 2A to maximize performance and flexibility.

The LTC3109EUF #PBF PMIC is designed for maximum energy efficiency and reliability in an ultra-low power application. All of its key functions are designed into one integrated device, reducing the design complexity and cost, while providing highly reliable and efficient power management. It is suitable for a wide range of applications such as wearables, medical devices, IoT devices, and other ultra-low power devices that require the most efficient energy management.
