Overview of TPS51120RHBR

Elevating power management to a new level, the TPS51120RHBR is a highly sophisticated dual, synchronous step-down controller that excels in delivering efficient and stable power for notebook computer systems. Powered directly from a three- or four-cell Li-ion battery, this controller offers high-power regulation and 5-V/3.3-V standby support for downstream circuitry. Featuring glitch-free switch over to SMPS, the on-board linear regulators ensure uninterrupted operation during standby mode. The controller's adaptive on-time control scheme, with pseudo-constant frequency support, enables versatile current mode operation and simplified loop compensation, enhancing overall efficiency. Additionally, the optional D-CAP mode operation, optimized for SP-CAP or POSCAP output capacitors, reduces the need for external compensation parts, further streamlining the design process. With dynamic UVP support and protection against voltage fluctuations and other safety features, the TPS51120RHBR guarantees reliable performance and stability across varying ambient temperatures
