UCC28251PWR

先进的PWM控制器，带有预偏置操作 Advanced PWM Controller With Pre-Bias Operation

With this current controller, developed by Texas Instruments, easily manage varying levels of output voltage entering your circuit. Its typical operating supply voltage is 12 V. With an output that has a voltage of -0.3 to 20.3 V, this is power management at its best. This current mode controller supports forward|full-bridge|half-bridge|push-pull topology. Its 2 PWM outputs produce a current of 200 mA. You can operate this at a switching frequency of 1800 kHz. This product will be shipped in tape and reel packaging for quick mounting and safe delivery. This device has a typical operating supply voltage of 12 V. Its minimum operating supply voltage of 4.7 V, while its maximum is 17 V. This current mode controller has an operating temperature range of -40 °C to 125 °C. This current mode controller"s maximum duty cycle is 100 %.
