Fujitsu MB3785A
The MB3785A is a PWM-based 4-channel switching regulator controller featuring high-precision, high-frequency capabilities. The third and fourth channels are suited for DC motor speed control. The triangular-wave oscillation circuit accepts a ceramic resonator, in addition to the standard method of oscillation using an RC network.| Part No. | MB3785A |
