The LM2576-3.3BU chip is a DC to DC switching regulator with an output voltage of 3.3V that is part of the category of integrated circuits called PMIC - Voltage Regulators - DC DC Switching Regulators.

The chip is designed to generate a low noise fixed output voltage, whose magnitude is selectable through external resistors. It is made with the most advanced integrated circuit technology, achieving high efficiency and a wide input voltage range to provide low output voltages for non-isolated applications.

The LM2576-3.3BU voltage regulator works with a factor of conversion from its input to its output. This voltage regulation factor is established in its integrated circuit, allowing a wide range of valid voltages at the input. It uses high speed Pulse Width Modulation (PWM) to regulate the output voltage.

One of the most notable characteristics of the LM2576-3.3BU is its wide input power range, which makes it versatile and suitable for systems that require a low supply voltage. This characteristic is especially helpful when dealing with multiple power sources, as it allows the chip to function as an adapter to adjust its output voltage/current to the corresponding power levels of the inputs.

The LM2576-3.3BU also offers a wide range of other features, including adjustable switching frequency, under voltage and overvoltage protection, current mode control, surge and inrush current limit, soft start, and more. Thanks to these features, the LM2576-3.3BU can be used in a wide range of applications.

The LM2576-3.3BU has a wide range of applications in many industrial, commercial and consumer electronics. It can be used for powering LED systems, for intermediate bus converter (IBC) supplies, for point-of-load (POL) converters, and for low voltage DC output applications. It is also suitable for powering computers, mobile phones, portable electronics and much more.

Due to its high efficiency, its wide input range, and its versatile features, the LM2576-3.3BU chip is a preferred choice when it comes to medium and low power DC-DC converters. It is the ideal solution for building systems that require a reliable and stable voltage source.
