Maxim Integrated MAX38650 nanoPower Buck Converter provides an ultra-low 390nA quiescent current and operates from a 1.8V to 5.5V input voltage. The MAX38650 supports load currents of up to 100mA with peak efficiencies of 95%. The MAX38650 offers high efficiency throughout the load range with a small total solution size. The device is ideal for battery applications where extended battery life is required.
The Maxim MAX38650 nanoPower Buck Converter supports 100% duty cycle operation allowing seamless transition as battery discharges and falls below the target output voltage. The MAX38650 utilizes a unique control scheme that allows ultra-low quiescent current and high efficiency over a wide output current range.
The MAX38650 Converter is offered in a space-saving, 1.58mm x 0.89mm, 6-pin wafer-level package (WLP) (2 x 3 bumps, 0.4mm pitch), and is specified over the -40°C to +125°C operating temperature range.
