STMicroelectronics L4970A 10A Switching Regulator Datasheet
The L4970A is a step-down monolithic power switching regulator delivering 10A at a voltage variable from 5.1 to 40V. Realized with BCD mixed technology, the device uses a DMOS output transistor to obtain very high efficiency and very fast switching times. It features reset and power fail for microprocessors, feed forward line regulation, soft start, limiting current, and thermal protection. The device is mounted in a 15-lead multiwatt plastic power package and requires few external components.
