MAX38640AENT+T

MAX38640AENT+T is a nanoPower buck converter. It is an ultra-low 330nA quiescent current buck (step-down) DC-DC converter operating from 1.8V to 5.5V input voltage and supporting load currents of up to 175mA, 350mA, 700mA with peak efficiencies of 96%. While in shutdown, there is only 5nA of shutdown current. The devices offer ultra-low quiescent current, small total solution size, and high efficiency throughout the load range. It is ideal for battery applications where long battery life is a must. It utilizes a unique control scheme that allows ultra-low quiescent current and high efficiency over a wide output current range. Typical applications include portable space-constrained consumer products, wearable devices, ultra-low-power IoT, NB IoT, and BLE, single li-ion and coin cell battery products and wired, wireless, industrial products.
