The MAX1522EUT-T is an integrated circuit (IC) component developed by Maxim Integrated. It is a step-up DC-DC converter specifically designed for portable devices requiring high efficiency and small size. This IC operates from a single lithium-ion (Li+) battery cell or three NiMH/NiCd cells, providing a fixed 3.3V output voltage.
One of the key features of the MAX1522EUT-T is its ability to deliver a maximum output current of 300mA, which is suitable for a range of portable applications. It achieves high efficiency by utilizing a PWM switching architecture and synchronous rectification. This helps to minimize power loss and maximize battery life.
The IC has a high switching frequency of up to 2.4MHz, allowing for the use of tiny surface-mount components. This, combined with a small package size of 6-pin SOT-23, contributes to the overall compactness of the design. Additionally, the MAX1522EUT-T operates in pulse-skipping mode during light loads to further enhance efficiency.
Furthermore, this IC includes a programmable soft-start feature, which allows users to control the inrush current during power-up. This feature prevents voltage spikes or other undesirable effects that might harm sensitive components. The MAX1522EUT-T also offers over-temperature and short-circuit protection, ensuring the safety and reliability of the device
