1 / 24 page LM3488 High Efficiency Low-Side N-Channel Controller for Switching Regulators General Description The LM3488 is a versatile Low-Side N-FET high perfor- mance controller for switching regulators. It is suitable for use in topologies requiring low side FET, such as boost, flyback, SEPIC, etc. Moreover, the LM3488 can be operated at extremely high switching frequency in order to reduce the overall solution size. The switching frequency of LM3488 can be adjusted to any value between 100kHz and 1MHz by using a single external resistor or by synchronizing it to an external clock. Current mode control provides superior band- width 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 over voltage protection. Power saving shutdown mode reduces the total supply current to 5µA and allows power supply sequencing. Internal soft-start limits the inrush current at start-up.
