概述

The TPS51120EVM-001 evaluation module utilizes the TPS51120 in a high efficiency, dual synchronous buck converter providing 5 V at 6 A and 3.3 V at 6 A from 8 V to 25 V input. The user’s guide describes the TPS51120EVM-001 performance in D-CAP™ mode and RDS(on) current sensing.

The TPS51120 is a highly sophisticated dual current mode synchronous step-down controller. It is a full featured controller designed to run directly off three to four-cell Li-ion battery and provide high power and 5 V and/or 3.3 V standby regulation for all the downstream circuitry in a notebook computer system.

High current, 100 mA, 5 V or 3.3 V on-board linear regulators have glitch-free switch over function to SMPS and can be kept alive independently during standby state. The pseudo-constant frequency adaptive on-time control scheme supports full range of current mode operation including simplified loop compensation, ceramic output capacitors as well as seamless transition to reduced frequency operation at light-load condition. Optional D-CAP™ mode operation optimized for SP-CAP or POSCAP output capacitors allows further reduction of external compensation parts.
