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. Features of the L4970A include reset and power fail for mi- croprocessors, feed forward line regulation, soft start, limiting current and thermal protection.

The L4970A is a 10A step-down monolithic power switching regulator that delivers 10A at a voltage that can vary from 5.1 to 40V. It has BCD mixed technology and uses a DMOS output transistor to achieve very high efficiency and very fast switching times. The L4970A has features such as 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. Its efficient operation at frequencies of up to 500KHz reduces the size and cost of external filter components.
