Description

The LM3488 is a versatile low-side N-FET high-

performance controller for switching regulators. This

device is designed for use in topologies requiring

low-side FET, such as boost, flyback, or SEPIC.

Moreover, the LM3488 can be operated at extremely

high switching frequency to reduce the overall design

size. The switching frequency of LM3488 can be

adjusted to any value from 100kHz to 1MHz by using

a single external resistor or by synchronizing the

device to an external clock. Current mode control

provides excellent 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 5µA and allows power supply

sequencing. Internal soft-start limits the inrush current

at start-up
