LM3488MM/NOPB General Description

The LM3488MM/NOPB is a versatile and high-performance low-side N-FET controller designed for switching regulators, offering exceptional adaptability and efficiency. Its suitability for topologies requiring a low-side FET, such as boost, flyback, or SEPIC, makes it a valuable asset in a variety of applications. Additionally, the LM3488MM/NOPB can operate at extremely high switching frequencies, contributing to a reduction in overall solution size and improved performance. The device's switching frequency can be easily adjusted within a wide range, from 100 kHz to 1 MHz, using a single external resistor or by synchronization to an external clock, providing precise control and flexibility. With current mode control that ensures superior bandwidth and transient response, alongside cycle-by-cycle current limiting, the LM3488MM/NOPB delivers reliable and precise operation. Furthermore, the device incorporates built-in thermal shutdown, short-circuit protection, and overvoltage protection, enhancing system safety and longevity. Its power-saving shutdown mode reduces total supply current to 5 µA and enables power supply sequencing, while internal soft-start limits inrush current at start-up, offering comprehensive functionality for efficient and controlled switching regulator operation
