Product Overview

The LM3488MM/NOPB is a versatile low-side N-FET High-performance Controller for switching regulator. This controller is suitable 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 solution size. The switching frequency of the controller can be adjusted to any value from 100kHz to 1MHz 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. This controller 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.
  • Current limit and thermal shutdown
  • Frequency compensation optimized with a capacitor and a resistor
  • Internal soft-start
  • Current mode operation
  • Under-voltage lockout with hysteresis
  • Green product and no Sb/Br
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
