IC REG BUCK 3.3V 3A TO263-5L

The LM3478MM is a versatile switching regulator controller designed to support multiple topologies such as boost, flyback, SEPIC, and inverting configurations. It is housed in a compact 8-pin VSSOP package, making it suitable for space-constrained applications. The device operates over a wide input voltage range and requires external components to set the desired output voltage and configuration. It features high switching frequency capability, enabling the use of smaller external components. The controller also includes protection features such as current limiting and thermal shutdown for reliable and efficient operation.
