NCP3134中文资料NCP3134: 2.9V to 5.5V, 4A, 2.2MHz, Integrated Synchronous DC-DC Step Down Converter数据手册ONSEMI规格书

描述 Description

The NCP3134 is a fully integrated synchronous buck converter capable of operating from 2.9V to 5.5V while delivering up to 4A. The NCP3134 operates at 2.2MHz, allowing for a smaller output filter and offering fast load transient response.The device can operate in DCM/CCM (higher efficiency at light loads) or Forced CCM mode to ensure fixed frequency operation. The device is offered in a small 3mm by 3mm QFN package.

特性 Features

Automatic DCM/CCM and FCCM operating modes
Improve efficiency at light loads or use fixed frequency operating mode
2.2MHz Switching Frequency
High switching frequency to minimize passives (inductor, capacitors)
3mm by 3mm QFN package
Small size reduce board space. QFN thermally enhance for power dissipation
Over/Undervoltage, Overcurrent, and Overtemperatureprotection
Protect IC against faults
Internal 1ms soft start
Reduce inrush current during start up
Safe start up into prebias output
Prevents reverse current flow from output capacitor
Up to 4A continuous current

应用 Application

5V and 3.3V POL applications

简介

NCP3134属于集成电路（IC）的稳压器-DC-DC开关稳压器。由制造生产的NCP3134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。
