Part Overview

Description
The TPS54494 is a dual, adaptive on-time D-CAP2™ mode synchronous buck converter. It enables system designers to complete the suite of various end equipment's power bus regulators with a cost-effective, low component count, and low standby current solution. The main control loops of the TPS54494 use the D-CAP2TM mode control which provides a very fast transient response with no external compensation components. The adaptive on-time control supports seamless transition between PWM mode at higher load conditions and Eco-mode™ operation at light loads. Eco-modeTM allows the TPS54494 to maintain high efficiency during lighter load conditions. The TPS54494 is able to adapt to both low equivalent series resistance (ESR) output capacitors such as POSCAP or SP-CAP, and ultra-low ESR, ceramic capacitors. The device provides convenient and efficient operation with input voltages from 4.5V to 18V.

  • Series

    Series, in the context of electronic components, refers to the arrangement of components in a circuit. When components are connected in series, they form a single path for current to flow through. The total resistance of a series circuit is the sum of the individual resistances of each component. Series connections are often used to control the flow of current in a circuit, as the total resistance can be adjusted by changing the number or type of components in the series.

  • Part Status

    Part Status is an electronic component parameter that indicates the availability and production status of a component. It is typically used to inform customers about the availability of a component, whether it is in production, end-of-life, or obsolete. Part Status can also provide information about any restrictions or limitations on the component's use, such as whether it is only available for certain applications or if it has been discontinued.

  • Moisture Sensitivity Level (MSL)

    Moisture Sensitivity Level (MSL) is a measure of the susceptibility of a surface mount electronic component to moisture-induced damage during soldering. It is classified into six levels, from 1 (least sensitive) to 6 (most sensitive). MSL is determined by the materials used in the component's construction, including the solderability of its terminals and the presence of moisture-absorbing materials. Components with higher MSL ratings require more stringent handling and storage conditions to prevent moisture absorption and subsequent damage during soldering.

  • Supply Voltage

    Supply Voltage is the voltage required to power an electronic component. It is typically measured in volts (V) and is specified in the component's datasheet. The supply voltage must be within the specified range for the component to function properly. If the supply voltage is too low, the component may not function at all. If the supply voltage is too high, the component may be damaged.

  • Output Voltage

    Output Voltage is the voltage level produced by an electronic component when it is operating. It is typically measured in volts (V) and can be either positive or negative. The output voltage of a component is determined by its design and the input voltage applied to it. For example, a voltage regulator will produce a fixed output voltage regardless of the input voltage, while an amplifier will produce an output voltage that is proportional to the input voltage.
