MAX253EUA+T

Product Overview

MAX253EUA+T from Analog Devices Inc./Maxim Integrated is a specialized power-management IC intended for transformer-driver use. The device is a 1 W transformer driver and is offered in a surface-mount 8-uMAX/uSOP package, corresponding to an 8-TSSOP/8-MSOP case with 3.00 mm width. It operates from 3.3 V or 5 V supply rails, with a supply current of 450 µA. The operating temperature range is -40°C to 85°C. These characteristics support compact transformer-based power conversion stages where a surface-mount driver, defined supply voltage options, and a defined temperature range are required.

Design & Procurement Notes

When selecting this transformer driver, confirm that the board supply is 3.3 V or 5 V and that the 450 µA supply current is compatible with the power budget. The -40°C to 85°C operating range should be compared with the expected ambient environment. The 8-uMAX/uSOP surface-mount package, with an 8-TSSOP/8-MSOP 3.00 mm width, influences pad layout, transformer placement, and clearance around the driver. Because the device is a 1 W transformer driver, transformer selection and PCB layout should be checked against the intended drive application. These design considerations help ensure that the package, supply, current, and temperature characteristics are matched to the application.
