    LT8714
    Bipolar Output Synchronous
    Controller with Seamless
    Four Quadrant Operation
    DESCRIPTION FEATURES
    Bipolar Output Cleanly Transitions Through 0V
    nn Output Can Source or Sink Current for Any
    Output Voltage
    nn CTRL Pin Externally Sets Output Voltage
    nn Wide Input Range: 4.5V to 80V
    nn Power Good Indication Pin (PG)
    nn Switching Frequency Up to 750kHz
    nn Can Be Synchronized to an External Clock
    nn High Gain EN Pin Accepts Slowly Varying Input Signals
    nn 20-Lead TSSOP Exposed Pad Package The LT®8714 is a synchronous PWM DC/DC controller
    designed for a four quadrant output converter. The output
    voltage cleanly transitions through zero volts with sourcing
    and sinking output current capability. nn The LT8714 is ideal for regulating to positive, negative,
    or zero volts when configured for the novel four quadrant
    topology. Applications include four quadrant power supplies, high power bidirectional current sources, active
    loads, and high power, low frequency signal amplification.
    In addition, the LT8714 incorporates a power good feature
    to let the user know if VOUT is above or below its target ...
