Overview

TPS5403是一款具有宽运行输入电压范围（4.5V至28V）的单片非同步降压稳压器。此器件执行内部斜坡补偿的电流模式控制来减少组件数量。 TPS5403还特有一个轻负载脉冲跳跃模式，此特性可在轻负载时减少为系统供电的输入电源的功率损失。可使用一个外部电阻器将此转换器的开关频率设定在50kHz至1.1MHz之间。引入了频率展频操作以减少EMI。添加了LX抗振铃来解决高频EMI问题。具有频率折返功能的逐周期电流限制在过载情况下保护集成电路(IC)。 The TPS5403 is a monolithic non-synchronous buck regulator with a wide operating input voltage range (4.5V to 28V). The device implements current mode control with internal slope compensation to reduce component count. The TPS5403 also features a light-load pulse skipping mode, which reduces power loss from the input supply powering the system under light-load conditions. The converter's switching frequency can be set between 50kHz and 1.1MHz using an external resistor. Frequency spread spectrum operation is incorporated to reduce EMI. LX anti-ringing is added to address high-frequency EMI issues. Cycle-by-cycle current limiting with frequency foldback protects the IC under overload conditions.
