Типовая схема включения OB2283
FEATURES
- Power on soft start reducing MOSFET Vds stress
- Frequency shuffling for EMI
- Extended burst mode control for improved efficiency and low standby power design
- Audinoise free operation
- Peak load operation with increased frequency
- Comprehensive protection coverage
- VCC Under Voltage Lockout with hysteresis (UVLO)
- VCC Over Voltage Protection (VCC OVP)
- Cycle-by-cycle over current threshold setting for constant output power limiting over universal input voltage range
- Over Load Protection (OLP) with autorecovery
- External (if NTC resistor is connected at PRT pin)or internal Over Temperature Protection (OTP) with latched shut down
- Output Over Voltage Protection(Output OVP) with latched shut down, and the OVP triggered voltage can be adjusted by the resistor connected between auxiliary winding and PRT pin
- Output diode short protection with autorecovery
- GND open protection with auto-recovery
