Fujitsu MB3769A
MB3769A is a pulse-width-modulation controller which is applied to fixed frequency pulse modulation technique. The MB3769A contains wide band width Op-Amp and high speed comparator to construct very high speed switching regulator system up to 700 kHz. The MB3769A provides stand-by mode at low voltage power supply when it is applied in primary control system.| Part No. | MB3769A |
