LM20333MHE/NOPB Description

Short technical summary and product information.

The LM20333MHE/NOPB from Texas Instruments is a 36V, 3A current mode synchronous buck regulator designed for efficient power conversion. It operates with an input voltage range of 4.5V to 36V and provides an adjustable output voltage down to 0.8V.

 

Key features include frequency synchronization from 250kHz to 1.5MHz, integrated power MOSFETs with low on-resistance (130mΩ/110mΩ), and peak efficiency up to 94%. The device supports pre-bias startup and has programmable soft-start functionality. It is housed in a 20-HTSSOP package suitable for surface mounting.

 

This regulator is ideal for applications requiring stable and efficient step-down voltage conversion. Its robust protection features, including overcurrent protection, thermal shutdown, and restart, ensure reliable operation in demanding environments. The current mode control and selectable compensation allow for design flexibility.
