HomeGeneral Description
KP401 is a secondary side synchronous rectifier controller, that replaced Schottky diodes by combined with an ultra low on-state resistance power switch for high-efficiency flyback converters. KP401 supports CCM, DCM and Quasi-Resonant Topologies based on the proprietary of “Self-Suitable Dead Time Control” technology. An integrated Error Amplifier with 1.25V reference voltage can replace TL431 for cost saving.
KP401 integrates protections of Under Voltage Lockout (UVLO), Primary-Side switching on time Expansion and Shrink Protection.
