Product Overview: TPS65261RHBR by Texas Instruments

The TPS65261RHBR is a high-performance, triple-output, synchronous step-down switcher integrated circuit (IC) designed and manufactured by Texas Instruments (TI). This advanced power management IC is tailored to meet the rigorous demands of complex digital systems that require multiple power rails with high efficiency and tight regulation.

At the heart of the TPS65261RHBR lies a versatile triple-channel regulator capable of delivering 3 A on the first channel and 2 A on each of the second and third channels. This configuration makes it an ideal solution for powering multi-core processors, FPGAs, DSPs, and other digital ICs that require separate voltage domains for core, I/O, and memory power.

The device operates over a wide input voltage range from 4.5 V to 18 V, making it suitable for a variety of applications including industrial, automotive, and telecommunications equipment. The TPS65261RHBR provides high efficiency and fast transient response, ensuring stable operation under dynamic load conditions.

Key features of the TPS65261RHBR include:

• Integrated high-side and low-side MOSFETs for each channel, which reduce external component count and simplify the power supply design.
• Adjustable switching frequency from 200 kHz to 2 MHz, allowing designers to optimize the performance for their specific application.
• Frequency synchronization capability to reduce electromagnetic interference (EMI) and optimize performance when used in systems with multiple power supplies.
• Power Good (PG) outputs for each channel, which provide system monitoring and sequencing capabilities.
• Thermal shutdown and overcurrent protection to safeguard the device and downstream components from damage under fault conditions.

The TPS65261RHBR is offered in a compact 32-pin VQFN package, which is ideal for space-constrained applications. Its thermal performance is enhanced by a PowerPAD™ on the underside of the package, which provides an efficient thermal path to the PCB.

With its robust feature set and high level of integration, the TPS65261RHBR by Texas Instruments is a comprehensive power management solution that delivers performance, efficiency, and reliability for advanced electronic systems.
