The TPS51120RHBR from Texas Instruments is a dual-channel synchronous buck controller. It is designed to manage power efficiently, offering a wide supply input voltage range from 4.5 V to 28 V.
Key electrical features include selectable D-CAP mode for fast transient response, selectable low ripple current mode, and selectable PWM-only/auto-skip modes. It also incorporates 3.3-V and 5-V 100-mA bootstrapped standby regulators with independent enables. The controller utilizes loss-less current sensing and offers an accurate current sense option. Internal soft-start, integrated VOUT discharge transistors, and an integrated 2-V reference are also included.
This device operates within a temperature range of -40°C to 85°C and is housed in a 32-VQFN (5x5) package, suitable for surface mount applications. The controller provides powergood status for each channel with a delay timer and includes a fault disable mode.
Its synchronous rectification capability and adaptive gate drivers with integrated boost diodes contribute to its overall efficiency and performance in various power supply designs.
