The LM2660MMX is a family of monolithic, integrated reactive power factor correction (PFC) dc-to-dc converters. It is an advanced power factor correction device that includes a unique intermediate-voltage-feedback (IVF) architecture to reduce the power inductor size and cost. The LM2660MMX family of ICs are designed to operate with an input voltage ra nge of 9V to 32V, providing an output voltage of 0.9V to 1V. They also feature under-voltage lockout, over-voltage protection, and short-circuit protection.

The LM2660MMX is suitable for applications where high efficiency and low profile are essential. It is suitable for use in an industrial lighting application, or for a custom power supply. The LM2660MMX enables designers to build high efficiency power supplies with a minimum amount of components.

The LM2660MMX is an excellent choice for AC/DC isolated current-mode converters. It provides high efficiency, low output voltage ripple, and low power losses. The device is protected against over-current, under-voltage, and over-voltage. The output current limit is adjustable, making it possible to achieve a wide variety of ratios between input and output currents.

The LM2660MMX provides integrated functions such as UVLO, MOSFET protection, over-voltage protection, and VCC_under voltage lockout. Input to output isolation is improved by the use of Digital I2C Interface (DII). This interface is used to provide accurate information about the voltage levels on the input side.

The LM2660MMX works by controlling the active power factor in an AC/DC converter. The device takes a constant input voltage (with ripple/sag) and regulates an output voltage regardless of load variations. This is achieved by varying the switching frequency so that the output voltage remains constant.

The LM2660MMX can tolerate up to a 48V supply for up to 0.7V output voltage and a 24V supply for up to 0.4V output voltage. This device integrates an I2C interface, enabling accurate regulation of output voltage and current.

The LM2660MMX has a simple and cost-effective PFCO architecture which allows the user to manage power losses in an isolated DC/DC isolated topology. High efficiency can be obtained with the device, as it is capable of managing a wide range of power levels.

The LM2660MMX is an excellent choice for applications in which the output voltage needs to remain constant regardless of changes in input voltage. It provides high efficiency, low output voltage ripple, and low power losses. The device is protected against over-current, under-voltage, and over-voltage. The output current limit is adjustable, making it possible to achieve a wide variety of ratios between input and output currents.
