MAX77837 Switching Current Buck-Boost Converter Analog Devices Inc. MAX77837 Switching Current Buck-Boost Converter is a nanoPower IC optimized for single-cell battery chemistries in wearable and Internet of Things (IoT) applications. MAX77837 operates on an input supply between 1.8V to 5.5V with output voltages (1.8V to 5.2V) set through resistors connected to two hardware control pins. Continuous conduction mode (CCM), skip mode, and low-power mode ensure high efficiency over a wide load current range. An ultra-low 430nA quiescent current (typical) and a shutdown current of 10nA (typical) make the buck-boost converter ideal for battery-powered applications requiring a long standby time.
