The LM2575T-12G is a switching regulator specifically designed to provide a regulated DC output voltage over an input voltage range of 4 V to 40 V. It is well suited to step-down applications, providing 12 V DC outputs with up to 1.5 A of output current.

The LM2575T-12G is a monolithic integrated circuit that contains an oscillator, switch, reference, and protected power switch. Functions such as frequency control, thermal shutdown, input voltage and current limiting, soft start, and output voltage monitoring are all built into the IC. It also features output voltage accuracy of ±2% from 0°C to 125°C.

The LM2575T-12G operates in two different modes of regulation. In the PFM mode, the IC will operate in a quasi-fixed frequency, allowing for a low ripple voltage at higher efficiencies than the continuous mode of operation. In the PWM mode, the IC will switch at a constant rate, maintaining greater regulation accuracy over the PFM mode. The device can switch up to 1.5A of constant load.

The LM2575T-12G is ideal for battery-operated and low-voltage applications. It is ideal for mobile phones and other high-end devices because of its high efficiency and low power usage. It is also extremely reliable with a typical life of 20,000 hours or more. It is available in a variety of packages to suit the application.

The LM2575T-12G is a versatile and reliable DC-DC switching regulator ideal for a wide range of applications. Because of its low power usage and high efficiency, it is well suited for mobile phones and other high-end devices. Furthermore, its wide input voltage range, adjustable switching frequency, and output voltage accuracy make it a great choice for applications where stability, performance, and flexibility are paramount.
