The LM2576HVS–ADJ provides the industry\'s most accurate output current limit of any step-down DC/DC regulator. Referred to as a "current limit regulator", it provides a much finer current control than any simple on/off system and helps to protect equipment from overloading. The device also features a high switching frequency, allowing it to target multiple outputs in a low profile design.

The LM2576HVS–ADJ can provide efficient and reliable regulation of input voltages as high as 40V and as low as 2.5V. The device utilizes a current-limit control loop and an innovative PWM control circuit to ensure crisp transient response that avoids excessive current or power during transients, overloads or short circuits of the output. The device offers current limiting as low as 20mA when input/output voltages are exactly matched. Current limits are also adjustable to prevent too much current being drawn which can cause outputs to be over-driven or overloaded.

The LM2576HVS–ADJ includes an integrated voltage regulator that is connected to a digital ground. The output voltage from the voltage regulator is fed to an internal error amplifier which compares the output voltage to a reference voltage and the error amplifier\'s output is used to control the PWM control circuit. The PWM control circuit then adjusts the duty cycle of the transistors, allowing the output voltage to be accurately held to the required voltage.

The LM2576HVS–ADJ uses an internal PWM controller to regulate the output voltage by controlling the switching of the external series diode and MOSFET. The result is a highly efficient and fast response regulator. The device can be synchronized to an external clock and it can be used with a wide range of input and output voltages.

The LM2576HVS-ADJ is a versatile and reliable, step-down DC/DC regulator. It can provide precision current limiting, fast transient response and low output noise, all in a low-profile package. This makes the device particularly well-suited for applications requiring high accuracy, efficient current limiting and fast transient response. The LM2576HVS-ADJ can be used in a variety of applications such as medical, industrial, telecommunications and automotive systems.
