TPS62867RQYR -- Buck Switching Regulator IC
The TPS62867RQYR is a high-performance synchronous step-down converter manufactured by Texas Instruments. It features a 2.4-V to 5.5-V input voltage range and is capable of delivering up to 6 A of continuous output current. The device is packaged in a compact 1.5-mm × 2.5-mm QFN (VQFN-HR) with a 0.5-mm pitch, making it suitable for space-constrained applications. It operates with a switching frequency of 2.4 MHz and supports both forced PWM and power save modes to optimize efficiency across a wide load range.
The TPS62867RQYR is designed with advanced DCS-Control topology, which combines the benefits of hysteretic and current-mode control schemes. This allows the device to achieve fast transient response, excellent load regulation, and tight output voltage accuracy of ±1%. The converter features internal high-side and low-side power MOSFETs with low on-resistance (11 mΩ and 10.5 mΩ, respectively), minimizing power loss and enhancing efficiency. Additional features include a power-good indicator, output voltage discharge, hiccup short-circuit protection, and thermal shutdown for robust operation.
The TPS62867RQYR is widely used in applications requiring high power density and efficiency, such as core power supplies for FPGAs, CPUs, ASICs, and video chipsets. It is also suitable for machine vision cameras, IP network cameras, solid-state drives, optical modules, and multifunction printers.
Selecting the TPS62867RQYR offers several advantages. Its compact size and high efficiency make it ideal for applications where space and thermal management are critical. The device’s ability to operate in 100% duty cycle mode and its seamless transition between PWM and power save modes ensure optimal performance across varying load conditions. Additionally, its comprehensive protection features, including hiccup mode and thermal shutdown, enhance system reliability. The TPS62867RQYR is RoHS compliant and supports custom design optimization using TI’s WEBENCH® Power Designer.
