支持预偏置模式、适用于离线应用的高级半桥/全桥 PWM 控制器 20-TSSOP -40 to 125

This current controller from Texas Instruments will generate a stable source of current for an external system or 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. Its 2 PWM outputs produce a current of 200 mA. This current mode controller supports forward|full-bridge|half-bridge|push-pull topology. This part offers a switching frequency of 1800 kHz in order to work properly. In order to ensure parts aren"t damaged by bulk packaging, this product comes in tube packaging to add a little more protection by storing the loose parts in an outer tube. 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"s maximum duty cycle is 100 %. This current mode controller has a minimum operating temperature of -40 °C and a maximum of 125 °C.
