MP6902
The Future of Analog IC Technology
Fast Turn-off Intelligent Controller
DESCRIPTION
The MP6902 is a Low-Drop Diode Emulator IC
for Flyback converters which combined with an
external switch replace s Schottky rectification
diodes for high efficie ncy. The chip regulate s
the forward drop of an external switch to about
70mV and switches it off as soon as the voltage
becomes n egative. MP6902 has a light-loa d
sleep mode that redu ces the quiescent current
to <300uA.
FEATURES
• Supports DCM and Quasi-Resonant
Flyback Converters
• Works with 12V Standard and 5V Logic
Level FETS
• Compatible with Energy Star, 1W Standby
Requirements
• V DD Range From 8V to 24V
• Fast Turn-off Total Delay of 20ns
• Max 400kHz Switching Frequency
• <300 μA Quiescent Current at Light Load
Mode
• Supports High-side and Low-side
Rectification
• Power Savings of Up to 1.5W in a Typical
Notebook Adapter
APPLICATIONS
• Industrial Power Systems
• Distributed Power Systems
• Battery Powered Systems
• Flyback Converters
