LM5018MR Description

Short technical summary and product information.

The Texas Instruments LM5018MR is a versatile DC/DC switching regulator designed for efficient power conversion. It operates within a wide input voltage range of 7.5 V to 100 V and can deliver up to 300 mA of output current.

 

This regulator utilizes a Constant On-Time (COT) control mode, eliminating the need for loop compensation and providing ultra-fast transient response. Key electrical specifications include a minimum input voltage of 7.5 V and a maximum of 100 V, with an adjustable output voltage ranging from 1.25 V to 90 V. The typical switch current limit is 0.7 A, and the maximum duty cycle is 90%.

 

The LM5018MR is designed for ease of use, featuring integrated high-side and low-side switches, eliminating the need for an external Schottky diode. It also includes adjustable undervoltage lockout (UVLO) and synchronous rectification for improved efficiency. The operating temperature range is -40°C to 125°C.

 

Available in WSON-8 and SO PowerPAD-8 packages, this surface-mount device is suitable for various board-mount applications. Its compact size and robust feature set make it a compelling choice for designers seeking reliable and efficient power solutions.
