ML4811 - High Frequency Power Supply Controller

This page provides the datasheet information for the ML4811, a member of the ML4810 High Frequency Power Supply Controller family.

Datasheet Summary

Features

  • The ML4810 and ML4811 High Frequency PWM Controllers are optimized for use in Switch Mode Power Supply designs running at frequencies to 1MHz. The ML4810/11 contain a unique overload protection circuit which helps to limit stress on the output devices and reliably performs a soft-start reset. These controllers are designed to work in either voltage or current mode and provide for input voltage feed forward. A 1.1V threshold current limit comparator provides a cycle-by-cycle current limit. An in.

May 1997 ML4810*, ML4811** High Frequency Power Supply Controller GENERAL DESCRIPTION FEATURES The ML4810 and ML4811 High Frequency PWM Controllers are optimized for use in Switch Mode Power Supply designs running at frequencies to 1MHz. The ML4810/11 contain a unique overload protection circuit which helps to limit stress on the output devices and reliably performs a soft-start reset. These controllers are designed to work in either voltage or current mode and provide for input voltage feed forward. A 1.1V threshold current limit comparator provides a cycle-by-cycle current limit. An integrating circuit “counts” the number of times the 1.1V limit was reached. A soft-start cycle is initiated if the cycle-by-cycle current limit is repeatedly activated.
