描述 Description

LX7167A is a step-down PWM Switching Regulator IC with integrated high side P-CH and low side N-CH MOSFETs.  The IC operates using a hysteretic control topology with a full load operating switching frequency of 3MHz allowing small output filter components while maintaining excellent dynamic load response.The operational input voltage range of LX7167A is from 3V to 5.5V.  The part has a Power Save Mode (PSM) that automatically transitions between PWM and PSM mode depending on the load current.  This allows the converter’s efficiency to remain high when load current drops.  There is a Power Good function to indicate the status of the IC.In the shutdown mode, the IC’s current consumption is reduced to less than 1µA and the output capacitor is discharged.Other features of the part are: a) Cycle-by-cycle current limit followed by HICCUP mode which reduces the overall power dissipation of the internal MOSFETs, b) thermal protection and internal digital soft start.The LX7167A is available in a 2mm x 2mm 8 pin exposed pad DFN package.Features:2.4A Step-down RegulatorOperational Input Supply Voltage Range: 3V-5.5VIntegrated PMOS and NMOSLoad Current from Zero to 2.4A3MHz Switching FrequencySKIP pulse to improve light load efficiencyInput UVLO and OV ProtectionEnable PinPower GoodInternal Soft-startCycle-by-Cycle Over Current ProtectionHiccup  Mode Operation Under FB UVLORoHS Compliant for Pb Free  ROHS, PB Free

简介

LX7167ACLD属于集成电路（IC）的稳压器-DC-DC开关稳压器。由制造生产的LX7167ACLD稳压器 - DC-DC 开关稳压器DC-DC 开关稳压器 PMIC（电源管理集成电路）产品族中的产品是元器件级设备，用于需要稳定 DC 输入电压和/或将其转换为不同幅度的输出电压的应用。这些器件与称为“控制器”PMIC 的类似产品的区别在于集成了主开关元件，设备提供的电力会通过该元件。
