The LM2575HVT-15/LB03 is a highly efficient, step-down voltage regulator brought to you by Texas Instruments, a leader in analog and digital semiconductor ICs. This regulator is part of the LM2575 series, which is known for its ease of use and robustness in a variety of applications. The device is designed to deliver up to 1A of output current with an output voltage of 15V.
Constructed with a fixed-frequency oscillator and requiring minimal external components, the LM2575HVT-15/LB03 simplifies the design of switch-mode power supplies. It integrates all the functions necessary for a buck regulator, including a high-efficiency step-down (buck) regulator, a 52 kHz fixed-frequency internal oscillator, thermal shutdown, and a unique on/off control.
The LM2575HVT-15/LB03 operates over a wide input voltage range from 4.75V to 60V, making it suitable for applications from simple low-voltage consumer electronics to complex automotive and industrial systems. Its thermal shutdown and current limit features ensure safe operation during overload conditions. Additionally, the regulator's low power standby mode, activated by pulling the ON/OFF pin low, significantly reduces power consumption when the output is not required.
This device is available in a TO-220 package, which is known for its good heat-sinking capabilities. This, combined with its high efficiency, means that the LM2575HVT-15/LB03 can be used in applications where minimal heat generation is crucial. It is also characterized by its fast transient response and excellent line and load regulation, which contribute to a stable and reliable power supply.
The LM2575HVT-15/LB03 is ideal for a wide range of applications, including but not limited to simple high-efficiency step-down regulators, efficient pre-regulators for linear regulators, on-card switching regulators, and positive to negative converter (Buck-Boost). With its robust design and reliable performance, this voltage regulator from Texas Instruments stands out as a solid choice for your power management needs.
