The 600-mA LM5017 is the first in a new family of step-down switching regulators that reduce PCB area and system cost, while improving high-voltage reliability in telecommunication, industrial, smart grid, and automotive systems.

Texas Instruments Incorporated (Dallas, TX) (TI) (NASDAQ: TXN) expands its high-voltage point-of-load product line by introducing the industry’s first 100-V synchronous buck regulator with integrated MOSFETs. The 600-mA LM5017 is the first in a new family of step-down switching regulators that reduce PCB area and system cost, while improving high-voltage reliability in telecommunication, industrial, smart grid, and automotive systems. Features include:

• Wide 9- to 100-V input voltage range, which improve system reliability in a variety of designs.
• 600-mA LM5017, 300-mA LM5018 and 100-mA LM5019 are pin compatible and support both non-isolated step-down and isolated power supply applications.
• COT control architecture that provides fast transient response and eliminates the need for loop compensation.
• Integrated high-side and low-side N-Channel MOSFETs, which improve efficiency and eliminate external Schottky diode.
• Integrated high-voltage startup regulator that provides bias power for internal operation of the IC and for integrated gate drivers.
• Peak current limit and over temperature detection protect the device from overload. Under voltage threshold and hysteresis can be independently programmed.
