IFX91041EJV集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

IFX91041EJV属于集成电路（IC）的稳压器-DC-DC开关稳压器。由英飞凌科技股份公司制造生产的IFX91041EJV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。

描述 Description

The IFX91041 series are monolithic integrated circuits that provide all active functions for a step-down (buck) switching voltage regulator, capable of driving up to 1.8A load current with excellent line and load regulation. These devices are suited for use in industrial applications featuring protection functions such as current limitation and overtemperature shutdown. Versions with a fixed 5.0V and 3.3V (IFX91041EJV50, IFX91041EJV33) output voltage as well as an adjustable device (IFX91041EJV) with 0.60V reference feedback voltage are available. The switching frequency of 370kHz allows to use small and inexpensive passive components. The IFX91041 features an enable function reducing the shut-down current consumption to

• 1.8A step down voltage regulator

• Output voltage versions: 5.0 V, 3.3 V and adjustable

• ± 2 output voltage tolerance (+-4 for full load current range)

• Integrated power transistor

• PWM regulation with feedforward

• Input voltage range from 4.75V to 45V

• 370 kHz switching frequency

• Synchronization input

• Very low shutdown current consumption (<2uA)

• Soft-start function

• Input undervoltage lockout

• Suited for industrial applications: Tj = -40 °C to +125 °C

• Green Product (RoHS compliant)
