Part Description
The LM3488 is a versatile low-side N-FET highperformance controller for switching regulators. This device is suitable for use in topologies requiring lowside FET, such as boost, flyback, or SEPIC. Moreover, the LM3488 can be operated at extremely high switching frequency to reduce the overall solution size. The switching frequency of LM3488 can be adjusted to any value from 100 kHz to 1 MHz by using a single external resistor or by synchronizing it to an external clock. Current mode control provides superior bandwidth and transient response, besides cycle-by-cycle current limiting. Output current can be programmed with a single external resistor. The LM3488 has built-in features such as thermal shutdown, short-circuit protection, and overvoltage protection. Power-saving shutdown mode reduces the total supply current to 5 µA and allows power supply sequencing. Internal soft-start limits the inrush current at start-up.
