The LM2576D2T-15G voltage regulator can be used in a wide range of applications due to its high efficiency, low noise, low output ripple, and 8kHz switching frequency.

Working Principle

The LM2576D2T-15G voltage regulator is a synchronous buck regulator, which means it converts a higher input voltage to a lower output voltage by switching current between the input and output. This type of voltage regulator works by cycling an internal switch between the higher input voltage and a capacitor connected to the output voltage. When the switch is in the closed position, current flows through the switch and charges the capacitor, raising the output voltage. When the switch is in the open position, current stops flowing and the voltage in the capacitor is maintained due to the action of the internal power MOSFET.

The LM2576D2T-15G voltage regulator offers an adjustable switching frequency of up to 8kHz, which allows the user to reduce EMI noise in sensitive applications. It also includes a variety of protection features including over-voltage, short-circuit protection, under-voltage lockout, and thermal shutdown, ensuring the highest level of safety and reliability.
