SP6019I Synchronous Rectifier Driver The fundamental SP6019I synchronous rectifier (SR) driver IC utilizes the principle of a "prediction" logic circuit. The IC deliberates previous cycle timing to control the SR in the present cycle by a "predictive" algorithm that makes adjustments to the turn-off time, in order to achieve maximum efficiency and avoid cross conduction at the same time.
Feature:
Offers higher efficiency than Schottky diodes (depending on the SR's driver configuration)
Drive all power MOSFETs
The predictive gate timing control
Minimum MOSFET body diode conduction
Synchronized with transformer secondary voltage waveform
Applications:
Servers and workstations
Storage area network power supplies
Telecommunication converters
Embedded systems
Industrial and commercial systems using high current processors
