Monolithic Power Systems MP86884-3
Intelli-Phase Solution (Integrated HS/LS FETs and Driver) in 6x6mm TQFN
Overview
| Topology | Buck Converter |
| Input voltage | 5-14 V |
| Switching frequency | 100-1000 kHz |
| Output 1 | 1.2 V / 55 A |
| IC revision | 1.02 |
Description
The MP86884 is a monolithic half-bridge with built-in internal power MOSFETs and gate drivers. It achieves 55A of continuous output current over a wide input supply range.Integration of the driver and MOSFETS results in high efficiency due to optimal dead time control and parasitic inductance reduction.The MP86884 is a Monolithic IC approach to drive up to 55A per phase. This very small 6mmx6mm TQFN device can operate from 100kHz to 1MHz.This device works with tri-state output controllers. It also comes with a generalpurpose current sense and temperature sense.The MP86884 is ideal for server applications where efficiency and small size are a premium.
