Product Details

The LT8714 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.

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 regulation voltage.

The LT8714’s switching frequency range can be programmed between 100kHz and 750kHz via a resistor from the RT pin to GND. A SYNC pin is also provided if the user would like to synchronize the part to an external clock. Additional features such as current limiting and soft-start are included. The LT8714 is available in a 20‑lead TSSOP package.
