Adjust the voltage level of your devices with this step down A4490EESTR-T DC to DC converter from Allegro MicroSystems. This converter has 3 outputs. It only needs a voltage of at least 4.5 V while not exceeding 34 V to effectively power your circuit. With an adjustable output that has a voltage of 0.8 to 5 V, this is power management at its best. Using a load regulation of 3.5% is needed for a programmable DC power supply. This part offers a switching frequency of 470 to 630 kHz in order to work properly. This product will be shipped in tape and reel packaging so that components can be mounted effectively. This converter has a minimum operating temperature of -40 °C and a maximum of 85 °C.
