L5973D High-efficiency step-down (buck) switching regulator with integrated power switch, capable of delivering up to 2.5 A output current.
Description
L5973D is a monolithic step-down switching regulator developed by STMicroelectronics. It integrates a power MOSFET and control circuitry, enabling efficient DC/DC conversion with a minimal number of external components.
The device operates over a wide input voltage range up to 36 V and can deliver more than 2 A output current depending on application conditions. The output voltage is adjustable from 1.235 V to 35 V, making it suitable for a wide range of power supply designs.
An internal oscillator sets a fixed switching frequency of 250 kHz, allowing the use of compact external components. The device uses a P-channel MOSFET, simplifying design and improving efficiency.
L5973D includes multiple protection features such as pulse-by-pulse current limiting, thermal shutdown, and protection against feedback disconnection, ensuring reliable and safe operation.
It is commonly used in consumer electronics, industrial systems, networking equipment, and DC/DC power modules.
