NCP3135中文资料2.9V 至 5.5V，5A 集成同步 DC-DC 步降转换器数据手册ONSEMI规格书

描述 Description

NCP3135 is a fully integrated synchronous buck converter capable of delivering up to 5A. The device operates from 2.9V to 5.5V, making them ideal for 3.3V and 5V bus applications. The NCP3135 offers high efficiency, fast load transient response, and can operate in CCM/DCM (automatic continuous/discontinuous modes) or FCCM (forced continuous conduction mode).High switching frequency reduces the output filter size. The device offers enable and power good indicator that can be used for sequencing. The NCP3135 is offered in a small 3mm x 3mm QFN package.

特性 Features

• Automatic DCM/CCM and FCCM operating modes
• Improve efficiency at light loads or use fixed frequency operating mode
• 1.1MHz 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
• Output range from 0.6V to 0.84Vin
• Flexibility allows same device for multiple applications
• 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 5A continuous current

应用 Application

• 5V and 3.3V POL applications
• servers/desktops/notebooks
• solid state drives
• base station/networking

简介

NCP3135属于集成电路（IC）的DCDC开关稳压器。由制造生产的NCP3135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。
