Description
OB2358L 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 flyback
converter applications in sub 27W range.OB2358L offers complete protection coverage
with automatic self-recovery feature including
Cycle-by-Cycle current limiting (OCP), over load
protection (OLP), over temperature protection
(OTP), over voltage protection and VDD under
voltage lockout (UVLO).Excellen
Features
- Power on Soft Start Reducing MOSFET Vds Stress.
