2 A SWITCHING REGULATOR

The L4972A is a stepdown monolithic power switching regulator delivering 2A at a voltage variable from 5.1 to 40V. \n 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 L4972 include reset and PWM LATCH FOR SINGLE PULSE PER PERIOD\nUNDER VOLTAGE LOCK OUT WITH HYSTERETIC TURN-ON\nSWITCHING FREQUENCY UP TO 200KHz\nVERY HIGH EFFICIENCY\nCONTINUOUS MODE OPERATION\nTHERMAL SHUTDOWN\nRESET AND POWER FAIL FUNCTIONS\nPRECISE 5.1V ± 2% ON CHIP REFERENCE\n2A OUTPUT CURRENT\n0 TO 90% DUTY CY;
