Overview
The LM3488QMMX/NOPB is a high-efficiency, low-side N-channel controller designed for switching regulators. It is manufactured by Texas Instruments and is available in an 8-pin VSSOP package. This controller features built-in protections such as thermal shutdown, short-circuit protection, and overvoltage protection. It also includes a power-saving shutdown mode that reduces the total supply current to 5 μA and allows for power supply sequencing. The internal soft-start function limits the inrush current at start-up, enhancing reliability and efficiency.
