Analog Devices LT8714

Description

The LT®8714 is a synchronous PWM DC/DC controllerdesigned for a four quadrant output converter. The outputvoltage cleanly transitions through zero volts with sourcingand sinking output current capability.The LT8714 is ideal for regulating to positive, negative,or zero volts when configured for the novel four quadranttopology. Applications include four quadrant power supplies,high power bidirectional current sources, activeloads, and high power, low frequency signal amplification.In addition, the LT8714 incorporates a power good featureto let the user know if VOUT is above or below its targetregulation voltage.The LT8714’s switching frequency range can be programmedbetween 100kHz and 750kHz via a resistor from the RT pinto GND. A SYNC pin is also provided if the user would liketo synchronize the part to an external clock. Additionalfeatures such as current limiting and soft-start are included.The LT8714 is available in a 20‑lead TSSOP package.
