Quality Control: Learn More
Texas Instruments LM3477AMMX is a versatile positive output DC-DC controller IC. This component supports both buck and buck-boost topologies, enabling efficient step-down and step-up/down voltage regulation. It features a switching frequency of 500kHz, a maximum duty cycle of 93%, and a transistor driver output type. The LM3477AMMX operates over a wide supply voltage range of 2.97V to 35V and is specified for junction temperatures from -40°C to 125°C. Control is managed via an Enable pin, and it is designed for single output phase operation. The device is packaged in an 8-VSSOP (8-TSSOP, 8-MSOP) for surface mounting. This controller is suitable for applications in the automotive and industrial sectors requiring robust power management solutions.
