内置2NMOS OB2358 MT6516
Power on Soft Start Reducing MOSFET VDS
Stress
Frequency Shuffling for EMI
Extended Burst Mode Control For ImprovingMT6238 combines a dedicated current
mode PWM controller with a high voltage
power MOSFET. It is optimized for high
performance, low standby power, and cost
effective off-line fly-back converter
applications in sub 27W range. MT6238
offers complete protection coverage with
automatic self-recovery feature including
Cycle-by-Cycle Current Limiting (OCP),
Over Load Protection (OLP), VDD Over
Voltage Clamp and Under Voltage
Lockout (UVLO). Excellent EMI
performance is achieved with frequency
shuffling technique together with soft
switching control at the totem pole gate
drive output. The tone energy at below
20KHZ is minimized in the design and
audio noise is eliminated during operation.
MT6238 is offered in DIP8 package.
