Application & Notes
A4412KLVTR-T by Allegro MicroSystems is a Buck, Buck-Boost IC commonly used in power supply designs, battery-powered devices, and DC-DC conversion modules. Input voltage up to 40V, output 1.3V. The 38-TFSOP (0.173", 4.40mm Width) Exposed Pad package with surface mount mounting is standard for compact designs. Pay attention to input/output capacitor selection and PCB layout — switching regulators are sensitive to trace inductance.
