DescriptionThe LM3488isa versatile low-side N-FET high-
performance controller for switching regulators. This
deviceis suitable for usein topologies requiring low-
side FET, such as boost, flyback, or SEPIC.
Moreover, the LM3488 can be operatedat extremely
high switching frequency to reduce the overall
solution size. The switching frequencyof LM3488 can adjustedto any value from 100 kHzto1 MHz by
usinga single external resistoror by synchronizingit an external clock. Current mode control provides
superior bandwidth and transient response, besides
cycle-by-cycle current limiting. Output current can be
programmed witha 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 currentto5 µA and allows power supply
sequencing. Internal soft-start limits the inrush current start-up.
