MP6924GS Monolithic Power Systems

MP6924, MP6924A Fast Turn-off, CCM/DCM Compatible Dual LLC Synchronous Rectifier with low Sleep Mode Current DESCRIPTION FEATURES The MP6924, MP6924A is a dual, fast turn-off, Works with Standard and Logic Level intelligent rectifier for synchronous rectification MOSFETs in LLC resonant converters. Compatible with Energy Star Fast Turn-Off Total Delay of 35ns The IC drives two N-channel MOSFETs, Wide 4.2V ~ 35V V Operating Range DD regulates their forward voltage drop to 175A Low Quiescent Current in Light-Load Vfwd(MP6924:45mV,MP6924A:29mV), and turns Mode the MOSFETs off before the switching current Supports CCM, CrCM, and DCM Operation goes negative. Supports High-Side and Low-Side The MP6924, MP6924A has a light-load Rectification function to latch off the gate driver under light- Power Savings of Up to 1.5W in a Typical load conditions, limiting the current to 175A. Notebook Adapter The MP6924, MP6924As fast turn-off enables Available in a SOIC-8 Package both continuous conduction mode (CCM) and APPLICATIONS discontinuous conduction mode (DCM). AC/DC Adapters The MP6924, MP6924A requires a minimal PC Power Supplies number of readily available, standard, external LCD and LED TVs components and is available in a SOIC-8 Isolated DC/DC Power Converters package. All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive. Table 1: MP6924A vs. MP6924 For MPS green status, please visit the MPS website under Quality Assurance.
