LM2598T-12

The LM2598T-12 is a simple DC-DC switching voltage regulator which can be used to regulate the output voltage of a switching regulator in order to allow efficient power conversion. It is designed to provide a constant output voltage regardless of load or line conditions. It can be configured to provide a wide range of output voltages from 1.5 V to 25 V, and can operate up to a maximum input voltage of 36 V.

Application Field

The LM2598T-12 is typically used in applications that require efficient power conversion at high reliability, such as consumer electronics and computer systems. It is particularly suited for applications which require low noise, such as laptop computers and audio equipment. Additionally, its wide input voltage range and high current output capability make it suitable for automotive electronics, battery management systems and industrial control applications.

Working Principle

The LM2598T-12 works by using pulse-width modulation (PWM) to control the output voltage. The switching transistor is driven by an internal oscillator, which generates a train of pulses of constant width. The duty cycle of these pulses is controlled by an internal voltage reference, which allows the output voltage to be accurately regulated. This duty cycle control, combined with a low-ripple output, ensures stable and efficient power conversion. The LM2598T-12 also incorporates several advanced features to improve performance, including over-voltage protection, thermal shutdown and adjustable soft-start time.

Conclusion

The LM2598T-12 is a versatile and reliable DC-DC switching voltage regulator. It has a wide range of applications and can provide a stable output voltage independent of line conditions. It is also easy to configure and has several integrated features which improve its performance and reliability.
