艾睿:
If you need to change voltage levels in your DC circuit design use the synchronous buck /pwm dc to dc controller TPS51221RTVR DC voltage controller from Texas Instruments. Its output produces a current of 20Max A. This DC voltage controller has 2 outputs. With an output that has a voltage of 1 to 12 V, this is power management at its best. This DC voltage controller has an input voltage of 4.5 to 28 V. It has a switching frequency of 333 kHz. Tape and reel packaging will encase this product during shipment, in order to ensure safe delivery and enable quick mounting of components. This DC voltage controller has a minimum operating temperature of -40 °C and a maximum of 85 °C.
