Texas Instruments LM5575 SIMPLE SWITCHER? 75V, 1.5A Step-Down Switching Regulator LM5575MHX

The LM5575MHX is a step-down switching regulator designed by Texas Instruments, capable of handling input voltages from 6V to 75V and delivering a continuous output current of 1.5A. It features an integrated 330m,Ѷ N-channel MOSFET, which enhances efficiency and reduces the number of external components required for design. The output voltage is adjustable down to 1.225V, with a feedback reference accuracy of 1.5%. This regulator employs an Emulated Current Mode control architecture, providing excellent line regulation and a fast load transient response. The operating frequency can be adjusted between 50kHz and 500kHz using a single resistor, allowing for optimization of size and efficiency. Additionally, it includes built-in protections such as cycle-by-cycle current limit, thermal shutdown, and remote shutdown capabilities. The LM5575MHX is housed in a 16-lead HTSSOP package with an exposed pad for improved thermal dissipation, making it suitable for automotive and industrial applications. It operates within a temperature range of -40¬8C to +125¬8C, ensuring reliability in various environments. This product is supported by Texas Instruments' WEBENCH design tools, facilitating easier integration into projects.
