The MCP19035-BAAAE/MF voltage mode PWM controller from Microchip Technology applies a control voltage to your circuit"s inputs, allowing for modulation of the circuit s frequencies. This voltage mode driver supports buck topology. Its single PWM output produces a current of 20000(Max) mA. It has a switching frequency of 300(Typ) kHz. 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 voltage mode driver"s maximum duty cycle is 85(Min) %. This voltage mode driver has an operating temperature range of -40 °C to 125 °C.
