Varying voltages can be harmful to some microprocessor-based circuits. The TPS40210DRCR current controller from Texas Instruments is a great tool to modulate these levels to meet your requirements. With an output that has a voltage of 5 to 260 V, this is power management at its best. This current mode controller supports boost|flyback topology. Its single PWM output produces a current of 400 mA. Its switching regulator has a frequency of 35 to 1000 kHz. In order to guarantee safe delivery and allow for quick mounting of this component after delivery, it will be enclosed in tape and reel packaging during shipment. This current mode controller has an operating temperature range of -40 °C to 125 °C. This device has a minimum operating supply voltage of 4.5 V and a maximum of 52 V. This current mode controller"s maximum duty cycle is 95 %.
