This MCP1631V-E/SS voltage mode PWM controller from Microchip Technology can control the PWM signal using an applied control voltage to the inputs. Its single PWM output produces a current of 250 mA. You can operate this at a switching frequency of 2000 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 0(Min) %. This device has a minimum operating supply voltage of 3 V and a maximum of 5.5 V. This voltage mode driver has a minimum operating temperature of -40 °C and a maximum of 125 °C.
