Product Overview: LM5017MR from Texas Instruments

The LM5017MR is a high-performance switching regulator from Texas Instruments designed for a wide range of applications. This device is a member of the LM5017 family of regulators that feature an advanced high-voltage buck regulator based on an innovative constant on-time (COT) control scheme.

The LM5017MR operates over an input range of 7.5 V to 100 V, making it an ideal choice for systems that experience large variations in supply voltage. It is capable of delivering up to 600 mA of continuous output current with excellent line and load regulation. The high-voltage capability of this regulator is particularly suitable for industrial, automotive, and telecommunications power systems.

This regulator integrates a 100 V N-Channel MOSFET, which enhances its efficiency and reduces external component count. The COT control scheme employed by the LM5017MR provides fast transient response and requires no loop compensation, which simplifies circuit design and reduces overall component count.

With a wide operating temperature range of -40°C to 150°C, the LM5017MR is robust and suitable for harsh environments. It also features built-in protection mechanisms such as thermal shutdown, input undervoltage lockout, output overvoltage protection, and cycle-by-cycle current limit, ensuring reliable operation under fault conditions.

The LM5017MR is available in a space-saving MSOP-8 PowerPAD™ package, which is designed for enhanced thermal performance. This compact package makes the LM5017MR a great choice for space-constrained applications.

Key features of the LM5017MR include:

• Wide input voltage range: 7.5 V to 100 V
• Integrated 100 V N-Channel MOSFET
• Constant on-time (COT) control with no loop compensation needed
