LM5122MHE/NOPB Description

Short technical summary and product information.

The Texas Instruments LM5122MHE/NOPB is a versatile DC/DC switching controller featuring a wide input voltage range from 3V to 65V, with a specific start-up requirement of 4.5V. This device is capable of generating output voltages up to 100V and supports bypass operation where the output voltage equals the input voltage. It employs peak-current-mode control for efficient regulation and offers a maximum switching frequency of 1 MHz.

 

Key features include synchronous rectification for improved efficiency, phase interleaving for multiphase capability, and adjustable UVLO (Under-Voltage Lockout). The controller also provides programmable soft start and hiccup-mode overload protection. It is housed in a 20-HTSSOP package suitable for surface mounting.

 

This controller is designed for applications requiring efficient step-up voltage conversion. Its robust integrated gate drivers and adaptive dead-time control contribute to reliable operation. The device operates within a temperature range of -40°C to 125°C (TJ).
