调整脉冲宽度调制器 Regulating Pulse Width Modulator
A solution to pulse-width modulation is this voltage mode PWM controller from Texas Instruments. This voltage mode driver supports boost|flyback|forward|full-bridge|half-bridge|push-pull topology. Its 2 PWM outputs produce a current of 100Max mA. It has a switching frequency of 400 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 49Typ %. This voltage mode driver has a minimum operating temperature of -55 °C and a maximum of 125 °C. This device has a minimum operating supply voltage of 4.5 V and a maximum of 35 V.
