View Datasheet Manufacturer Site View Pricing & Stock

The L4970A is a stepdown 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 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.Efficient operation at switching frequencies up to 500KHz allows reduction in the size and cost of external filter components.
