MP86961 TM 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 Wide 4.5V to 21V Operating Input Range built-in internal power MOSFETs and gate 20A Output Current driver. It achieves 20A continuous output Simple Logic Interface(5.0V) current over a wide input supply range. Operate from 100kHz to 1MHz Accepts 3-state PWM Input Integrating the Driver and MOSFETs results in Suitable for single-/multi-phase operation high efficiency due to optimal dead time control Available in a 5mm x 5mm QFN Package and parasitic inductance reduction. ROHS6 Compliant The MP86961 is a Monolithic IC designed to drive up to 20A per phase. Housed in a very APPLICATIONS small 5x5mm QFN Packge, this device can be Power modules operated from 100kHz to 1MHz. Notebook, Core Voltage The IC is intended to work with 5V tri-state Graphic Card Core Regulators output controllers. All MPS parts are lead-free and adhere to the RoHS directive. For MPS green status, please visit MPS website under Quality Assurance. MPS and The The MP86961 is ideal for notebook applications Future of Analog IC Technology are Registered Trademarks of Monolithic where efficiency and small size are a premium. Power Systems, Inc.
