Analog Devices Inc.

The MAX38650 is a nanoPower, ultra-low 390nA quiescent current, buck (step-down) DC-DC converter operating from 1.8V to 5.5V input voltage and supporting load currents of up to 100mA with peak efficiencies of95%. While in shutdown, there is only 5nA of shutdown current. The device offers ultra-low quiescent current, small total solution size, and high efficiency throughout the load range. The device is ideal for batteryapplications where long battery life is a must. The MAX38650 supports 100% duty cycle operation allowing seamless transition as battery discharges and falls below the target output voltage. The MAX38650 utilizesa unique control scheme that allows ultra-low quiescent current and high efficiency over a wide output current range. The device is offered in a space-saving, 1.58mm x 0.89mm, 6-pin wafer-level package (WLP) (2 x 3bumps, 0.4mm pitch). The part is specified over the -40°C to +125°C operating temperature range.ApplicationsLow-Voltage Industrial ApplicationsPortable Space-Constrained Consumer ProductsSingle Li-ion and Coin Cell Battery ProductsWearable Devices, Ultra-Low-Power IoT, NB IoT, and Bluetooth Low Energy (BLE)Wired, Wireless, Industrial Products
