Please note: The following spec sheet / information is provided by the manufacturer and may cover several different items and/or products. I am offering the part listed in the heading and picture ONLY.
The L4972A is a step down monolithic power switching regulator delivering 2A 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 efficiencyand very fastswitching times. Features of
the L4972A include reset and power fail for microprocessors, feed forward line regulation, soft start, limiting current and thermal protection. The device is mounted in a Powerdip 16 + 2 +2 plastic packages and requires few external components.
Efficient operation at switching frequencies up to 200KHz allows reductionin the size and cost of external filter component.
* 5.1V TO 40V OUTPUT VOLTAGE RANGE
* INTERNAL FEED-FORWARD LINEREG.
* PRECISE 5.1V ± 2% ON CHIP REFERENCE
* RESET AND POWER FAIL FUNCTIONS
* UNDER VOLTAGE LOCK OUT WITH HYSTERETIC TURN-ON
PWM LATCH FOR SINGLE PULSE PER PERIOD
* SWITCHING FREQUENCY UP TO 200KHz
