The TPS51427ARHBR from Texas Instruments is a dual-output synchronous D-CAP buck controller optimized for notebook power systems. This device features a wide input voltage range from 5.5V to 28V, enabling flexibility in power supply designs. It supports dual fixed or adjustable SMPS outputs, with Channel 1 ranging from 0.7V to 5.9V and Channel 2 from 0.5V to 2.5V.
The controller utilizes D-CAP mode for fast transient response and advanced ramp compensation for low output ripple. It offers selectable switching frequencies and supports various operational modes including PWM-Only, OOA, and Auto-Skip. The TPS51427ARHBR is designed for efficient operation with a typical quiescent current of 0.0001A and a maximum duty cycle of 90%.
Packaged in a 32-VQFN (5x5 mm) with an exposed pad, this controller is suitable for surface mount applications. It operates within a temperature range of -40°C to 85°C. Key features include synchronous rectification, power good indication, and integrated soft start functionality. The OOB function is disabled in this specific part number; refer to TPS51427 for the OOB-enabled version.
