LM2575HVN-15/NOPB

LM2575HVN-15/NOPB is a voltage regulator, which belongs to the DC-DC switching regulators type within the wider Power Management Integrated Circuit (PMIC) category. It is a series of high-voltage (50V) step-down regulator that requires minimal external components to set up a reliable robust circuit. The LM2575 are able to output up to 1.5A of continuous output current, and due to internal limit, the maximum operating temperature is 85°C. It is designed to provide a constant output voltage of either 5V, 12V, or 15V adjustable over an input voltage range of up to 50V.

The LM2575HVN-15/NOPB Application Field mainly consists of industrial and commercial applications, such as distributed power systems, telecom, flat panel displays, FPGA and DSP applications, portables and mobile electronics, audio amplifiers, LAN and WAN systems, automotive, and consumer electronics. It is mainly used in memory, core logic circuits, and FPGAs and microprocessors.

The Working Principle of the LM2575HVN-15/NOPB starts with the input voltage being applied to the input of a regulating circuit. This regulating circuit is typically a feedback system consisting of an op-amp, comparator and reference, or a bandgap reference. The output voltage is then adjusted through the feedback loop, utilizing the output of the comparator or reference. The feedback loop is designed such that the output voltage is always maintained at the desired level, regardless of the input voltage, temperature or load conditions.

The LM2575HVN-15/NOPB also features internal current-limit, short-circuit protection, thermal-shutdown and soft-start. Soft-start is an important feature as it limits the inrush current and prevents cross-conduction in the MOSFET during the power-on state. The LM2575HVN-15/NOPB also implements an over-voltage protection (OVP) to ensure safe operation, as well as output over-voltage protection (OVP), short-circuit protection (SCP) and over-temperature protection (OTP).

The LM2575HVN-15/NOPB is an ideal choice for low-power, distributed power applications. It offers exceptional performance over wide input and output voltages and temperatures, combined with a wide range of features to ensure maximum reliability and ease of use. It is a convenient, reliable, and cost-effective solution for reliable power delivery for a wide range of applications.
