Présentation
Description
The MAX17220ELT+T is a DC-DC boost converter from Maxim Integrated, designed for ultra-low quiescent current applications. It operates with an input voltage range of 0.4V to 5.5V and provides an adjustable output voltage, making it suitable for battery-powered devices. The device features a high-efficiency synchronous boost architecture with a low quiescent current of 0.5µA, maximizing battery life.
Key features include True Shutdown™ mode, which disconnects the output from the input when in shutdown, preventing leakage current. The MAX17220ELT+T also integrates an internal synchronous rectifier, eliminating the need for an external Schottky diode, which reduces component count and cost. It offers protection features like output over-voltage protection, short-circuit protection, and thermal shutdown.
Packaged in a small, 6-pin thin SOT23 package, the MAX17220ELT+T is ideal for space-constrained applications such as wearables, medical devices, and IoT sensors. Its efficiency and compact design make it a preferred choice for designers looking to extend battery life in portable applications.
