SP6038
SP6038 is High Performance Synchronous Rectifying Converter manufactured by SYNC POWER.
DESCRIPTION
SP6038 is a high performance and tightly integrated secondary side synchronous rectifier for switching mode power supply system. It bines a much lower voltage drop N-channel MOSFET to emulate the traditional diode rectifier at the secondary side of Flyback converter, The fundamental of SP6038 synchronous rectifier (SR) driver IC is based on our U.S. patented methods that utilize the principle of “prediction” logic circuit. The IC deliberates previous cycle timing to control the SR in present cycle by “predictive” algorithm that makes adjustments to the turn-off time, in order to achieve maximum efficiency and avoid cross-conduction at the same time. The SP6038 is capable to adapt in almost all existing Resonance converters with few adjustments considered necessary.
