OB2283 is a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback converter applications. PWM switching frequency at normal operation is internally fixed and is trimmed to tight range. At no load or light load condition, the IC operates in extended ‘burst mode’ to minimize switching.
■ Power on soft start reducing MOSFET Vds stress
■ Frequency shuffling for EMI
■ Extended burst mode control for improved
efficiency and low standby power design
■ Audio noise free operation
■ Peak load operation with increased frequency
■ Comprehensive protection coverage
o VCC Under Voltage Lockout with hysteresis (UVLO)
o VCC Over Voltage Protection (VCC OVP) o Cycle-by-cycle over current threshold
setting for constant output power limiting over universal input voltage range o Over Load Protection (OLP) with autorecovery o External (if NTC resistor is connected at PRT pin)or internal Over T.
