DC Switching Voltage Regulators

LM76003RNPT Description

The LM76003RNPT from Texas Instruments is a high-performance, 3.5A synchronous buck regulator designed for demanding power management applications. This adjustable output DC-DC converter operates over a wide input voltage range (3.5V to 60V), making it suitable for industrial, automotive, and telecom systems. With a switching frequency range of 300kHz to 2.2MHz, it offers flexibility for optimizing efficiency and board space. The device features a positive output configuration, delivering 1V to 57V with high efficiency due to its integrated synchronous rectifier. Packaged in a 30-pin WQFN (Wettable Flank), it ensures reliable surface-mount assembly and complies with ROHS3 and REACH standards.

LM76003RNPT Features

• Wide Input Range: Supports 3.5V–60V, ideal for 12V/24V/48V bus systems.
• High Output Current: 3.5A continuous with synchronous rectification for improved efficiency.
• Adjustable Output: 1V to 57V for versatile design needs.
• Programmable Frequency: 300kHz–2.2MHz enables noise/performance trade-offs.
