  • The L296 and L296P are stepdown power switching regulators delivering 4 A at a voltage variable from 5.1 V to 40 V.

    Features of the devices include soft start, remote inhibit, thermal protection, a reset output for microprocessors and a PWM comparator input for synchronization in multichip configurations.
    The L296P incudes external programmable limiting current.
    The L296 and L296P are mounted in a 15-lead Multiwatt® plastic power package and requires very few external components.
    Efficient operation at switching frequencies up to 200 KHz allows a reduction in the size and cost of external filter components. A voltage sense input and SCR drive output are provided for optional crowbar overvoltage protection with an external SCR.

    Key Features

    • EXTERNAL PROGRAMMABLE LIMITING CURRENT (L296P)
    • RESET OUTPUT
    • INPUT FOR REMOTE INHIBIT AND SYNCHRONUS PWM
    • CONTROL CIRCUIT FOR CROWBAR SCR
    • THERMAL SHUTDOWN
    • VERY FEW EXTERNAL COMPONENTS
    • VERY HIGH EFFICIENCY (UP TO 90 %)
    • 4 A OUTPUT CURRENT
    • 0 TO 100 % DUTY CYCLE RANGE
    • 5.1 V TO 40 V OUTPUT VOLTAGE RANGE
    • SWITCHING FREQUENCY UP TO 200 KHz
    • SOFT START
    • PRECISE (±2 %) ON-CHIP REFERENCE
