The LM2590HVT-3.3 is a dc-dc switching regulator from the National Semiconductor. It is a member of their Power Management and Interface (PMIC) category, specifically their Voltage Regulators and DC- DC Switching Regulators class.

This device has many applications ranging from communications and computers to consumer electronics, power electronics and green power applications. Most notably, the LM2590HVT-3.3 is commonly used in LED lighting designs, as it offers a wide VIN range and low-cost solution.

The LM2590HVT-3.3 is capable of providing a constant output current no matter what input voltage is applied. This makes it an ideal solution for fluctuating voltage applications, as it maintains a steady output current over the varying input range.

The LM2590HVT-3.3 is a Buck converter, meaning that it operates by switching the current on and off to its output. This enables the device to step down an input voltage from higher values to its output voltage value, typically 3.3V in this case. This device uses Pulse Width Modulation (PWM) to control the desired output voltage, and is therefore able to convert the applied voltage to a required voltage level.

Being a single chip solution, it also offers a great degree of efficiency greater than 85 percent, making it ideal for power-sensitive applications. Additionally, it is capable of operating in a wide temperature range and has a built-in over temperature protection feature.

The LM2590HVT-3.3 is also capable of providing an adjustable voltage output, which can be adjusted in the range of 2.375V to 5.5V using a single resistor. This allows for greater control and flexibility, making it suitable for a wider variety of applications. It also offers other features such as thermal shutdown, short circuit protection, surge protection and adjustable soft-start.

The LM2590HVT-3.3 is a cost-effective, high performance solution to many of today’s power-sensitive applications. It is a robust, single chip solution that provides a high efficiency and cost-effective solution to many types of power complications. It is made with the National Semiconductor’s reliable technology, making it suitable for the most demanding applications.
