MP86961DU-LF-Z

TM MP86961 20A, 27V Intelli-Phase Solution (Integrated HS/LS FETs and Driver) in a 5x5mm QFN The Future of Analog IC Technology DESCRIPTION FEATURES The MP86961 is a monolithic Half Bridge with built-in internal power MOSFETs and gate driver. It achieves 20A continuous output current over a wide input supply range. • • • • • • • • Integrating the Driver and MOSFETs results in high efficiency due to optimal dead time control and parasitic inductance reduction. The MP86961 is a Monolithic IC designed to drive up to 20A per phase. Housed in a very small 5x5mm QFN Packge, this device can be operated from 100kHz to 1MHz. Wide 4.5V to 21V Operating Input Range 20A Output Current Simple Logic Interface(5.0V) Operate from 100kHz to 1MHz Accepts 3-state PWM Input Suitable for single-/multi-phase operation Available in a 5mm x 5mm QFN Package ROHS6 Compliant APPLICATIONS • • • The IC is intended to work with 5V tri-state output controllers. Power modules Notebook, Core Voltage Graphic Card Core Regulators All MPS parts are lead-free and adhere to the RoHS directive.
