LINEAR TECHNOLOGY LT8714EFE#PBF 芯片, 同步, 直流/直流控制器, 750KHZ, TSSOP-20 新
The is a bipolar output synchronous controller with seamless four quadrant operation in 20 pin TSSOP package. 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. It 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. It also features current limiting and soft-start.
