NCP3134数据手册集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF

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
