Introduction

The LM2599SX-3.3 is a step-up DC-to-DC switching regulator that provides up to 3.3V power supply output at a very low cost. It is designed to provide a robust 3.3V supply that can be used as a standby voltage supply as well as a primary voltage source. It is capable of regulating either a constant voltage or current output, depending on the application.

Application Field

The LM2599SX-3.3 is well suited for low-cost applications, such as PC motherboards, notebook computers, digital cameras and other mobile electronics. It can also be used to provide standby power for home appliances and other domestic electronics. Additionally, it can be used to provide an intermediate voltage between a large voltage source and a low-line voltage source as an efficient way to get a variable output.

The LM2599SX-3.3 can also be used in motor control applications. In this case, it can be used to accurately regulate the motor’s speed and to maintain the desired speed even when the input voltage varies significantly. It is also useful in providing power to low-voltage motors in remote locations, such as robotic applications.

Working Principle

The LM2599SX-3.3 operates using a PFM (Pulse-Frequency Modulation) control scheme. This makes it very efficient in its performance, resulting in less power usage and longer battery life. The regulator takes the input voltage from the battery and switches it on and off in quick pulses, effectively regulating the output voltage. The Pulse-Frequency Modulation scheme is based on the detection of the load current at the output of the device, with the regulator controlling the frequency of the pulses with a feedback circuit.

The LM2599SX-3.3 can be used in both voltage and current regulating applications, thanks to its’ adjustable reference voltage and current sensing circuitry. The reference voltage can be set up by two external resistor divider networks, and the current sensing is via a dedicated pin. With this feature, the device can provide precise voltage and current regulation, which is necessary in some applications such as motor speed control.

The LM2599SX-3.3 is designed to provide an efficient and reliable 3.3V power solution at a very low cost. Its’ PFM control scheme ensures good efficiency and long battery life, while its adjustable reference voltage and current sensing make it suitable for both voltage and current regulation applications. It is suitable for use in a wide range of applications, such as PC motherboards, notebook computers, digital cameras and other mobile electronics.
