3.5A Switching Voltage Regulator
Description
The L4974Aisa stepdownmonolithicpowerswitching
regulator delivering 3.5A 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 fast switching times. Features of
the L4974A include reset and power fail for microprocessors,
feed forward line regulation, soft start,
limiting current and thermal protection. The device
is mounted in a Powerdip16 + 2 + 2 plasticpackage
and requires few external components. Efficient
operation at switching frequencies up to 200KHz
allows reductionin the size andcost of external filter
component.
Features
• 3.5A OUTPUT CURRENT
• 5.1V TO 40V OUTPUT VOLTAGE RANGE
• 0 TO 90% DUTY CYCLE RANGE
• INTERNAL FEED-FORWARD LINE REG.
• INTERNAL CURRENT LIMITING
• PRECISE 5.1V ± 2% ON CHIP REFERENCE
• RESET AND POWER FAIL FUNCTIONS
• INPUT/OUTPUT SYNC PIN
• UNDER VOLTAGE LOCK OUT WITH HYSTERETIC TURN-ON
• PWM LATCH FOR SINGLE PULSE PER PERIOD
• VERY HIGH EFFICIENCY
• SWITCHING FREQUENCY UP TO 200KHz
• THERMAL SHUTDOWN CONTINUOUS MODE OPERATION
Package : Powerdip ( 16 + 2 + 2 )
