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.
