  • Point-of-load regulation

The TPS62095RGTR from Texas Instruments is a 4A synchronous step-down converter optimized for high efficiency and small solution size. Using DCS-Control topology, it achieves excellent load transient performance with accurate output voltage regulation. The device operates from 2.5V to 5.5V input with adjustable output from 0.8V to VIN, making it ideal for point-of-load regulation in notebooks, SSDs, and battery-powered systems. The 20uA quiescent current in power save mode and 95% peak efficiency minimize power loss across the entire load range.

The TPS62095RGTR uses Texas Instruments’ DCS-Control (Direct Control with Seamless transition) topology combining voltage-mode and current-mode control. In PWM mode at heavy loads, the device operates at a fixed 1.4MHz switching frequency with current-mode control for precise regulation. At light loads, it seamlessly transitions to power save mode with reduced switching frequency while maintaining output regulation. The 100% duty cycle capability allows the high-side switch to stay on continuously when the input voltage approaches the output, minimizing dropout. The adjustable soft-start controls output voltage ramp-up, and the power good output indicates regulation status. Output tracking allows coordinated power sequencing with other rails.
