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 …
