MP1654L

16V, 4A, 600kHz, High-Efficiency, Synchronous Step-Down Converter in an SOT563 Package

详情

The MP1654L is a fully integrated, high-frequency, synchronous, rectified, step-down switch-mode converter with internal power MOSFETs. The device offers a very compact solution that achieves up to 4A of continuous output current (I_OUT), with excellent load and line regulation across a wide input voltage (V_IN) range. The MP1654L uses synchronous mode for higher efficiency across the I_OUT load range.

Constant-on-time (COT) control operation provides very fast transient response, easy loop design, and very tight output regulation.

Full protection features include short-circuit protection (SCP), over-current protection (OCP), under-voltage protection (UVP), and thermal shutdown.

The MP1654L requires a minimal number of readily available, standard external components, and is available in a space-saving SOT563 (1.6mmх1.6mm) package.

【调试经验分享】DCDC芯片没有输出怎么办？

DCDC是如今电路供电的主要方式，工程师朋友们有时候会遇到DCDC没有输出的情况而不知道如何解决，下面给大家分享一些调试经验。 1.检查芯片是输入引脚的电压是否正常。芯片的输入电压过低的话将无法正常工作，过高则会损坏芯片。检查时，最好用示波器测量输入电容端或者芯片输入引脚的电压波形，看输入电压是否...

MP4575芯片无输出

目前在使用一片MP4575芯片时，输入电压25V，输出电压12V，带载1A，正常测试纹波，SW波形，使用一段时间后，突然电压无输出，SW无波形输出。测试该芯片引脚对地阻抗与可正常电压输出的MP4575芯片基本无差异。芯片表面也无损坏。请问会是什么原因导致的？2021-07-01_1722261187...
