TPSM82480MOPR

TPSM82480是一款适用于低厚度负载点电源的同步降压直流/直流转换器模块。2.4V至5.5V的输入电源范围使其既可以通过典型的3.3V或5V接口电源运行，也可以通过低至2.4V的备份电路运行。 输出电流最大可达6A，由每相各为3A的两相电源持续提供，能够以异相运行，显著降低脉冲电流噪声。 TPSM82480可在超轻负载时自动进入省电模式，并能保持高效率。其中包含自动增加/减少相位功能，具体使用一个相位还是两个相位视实际负载情况而定。可通过“模式”功能关闭省电模式。 器件可提供电源正常信号和可调软启动。此外，该器件还具有温度正常信号指示内部温度过高。通过VSEL引脚可将输出电压更改为预选值。TPSM82480能够以100%的占空比模式运行。

TPSM82480 is a high efficiency synchronous switched mode step-down converter module based on a 2-phase peak current control topology. It is designed for smallest solution size low-profile applications, converting a 2.4 V to 5.5 V input voltage into a lower 0.6 V to 5.5 V output voltage. While an outer voltage loop sets the regulation threshold for the inner current loop, based on the actual VOUT level, the inner current loop regulates to the actual peak inductor current level for every switching cycle. The regulation network is internally compensated. While the ON-time is determined by duty cycle, inductance and cycle peak current, the switching frequency of typically 2.2 MHz is set by a predicted OFF-time. The device features a Power Save Mode (PSM) to keep the conversion efficiency high over the whole load current range. The TPSM82480 is a 2-phase converter, sharing the load among the phases. Identical in construction, the second phase control is connected with an adaptive delay to the first phase. Both the phases use the same regulation threshold and cycle-by-cycle peak current setpoint. This ensures a phase-shifted as well as current - balanced operation. Using the advantages of the 2-phase topology, a 6-A continuous output current is provided with high performance and as small as possible solution size.
