LM2599SX-ADJ Integrated Circuits (ICs)

The LM2599SX-ADJ is a general-purpose, adjustable voltage regulator. It is ideal for applications in communications and networking as well as data acquisition and test equipment. It offers a wide input voltage range of 40 V to 90 V and a maximum output current of 3 A. The LM2599SX-ADJ also offers various protection features, such as overvoltage protection, undervoltage lockout, cycle-by-cycle current limit protection and thermal shutdown. The device is capable of delivering 5 V, 12 V or adjustable output voltages from 1.2 V to 35 V.

The LM2599SX-ADJ is a DC-DC switching regulator, which means it switches at high frequencies to deliver the desired output voltage. The integrated switching frequency is usually set to 200 kHz, allowing for a small inductor and capacitors. It also has a built-in internal synchronous rectifier to ensure better efficiency. It offers adjustable output voltage, programmable soft start, output power good signal and over-temperature protection.

The LM2599SX-ADJ is a synchronous buck switching regulator that employs a pulse-width modulation (PWM) control architecture. It converts an input voltage of 40 V to 90 V to a lower regulated output voltage. In order to produce the desired output voltage, the device regulates the current through an internal high-side MOSFET and an internal synchronous rectifier. The LM2599SX-ADJ incorporates a single-ended primary-inductor converter (SEPIC) topology which allows input voltage to be either higher or lower than the output voltage.

The LM2599SX-ADJ features an adjustable soft-start feature which slowly ramps up the output voltage after power-up and minimizes inrush current. Additionally, it features an output power good signal that indicates when the output voltage has reached its programmed voltage. The LM2599SX-ADJ also offers cycle-by-cycle current limit protection, over-voltage protection, under-voltage lockout and thermal shutdown.

The LM2599SX-ADJ is an ideal choice for power management in high-end networking and computing applications. It has a high switching frequency and small size, making it suitable for use in tight-space designs. Furthermore, the device offers adjustable output voltage, programmable soft start, output power good signal and various protection features, making it an ideal choice for system power supplies.
