OB2365D
DESCRIPTION
FEATURES
OB2365D is a highly integrated current mode
- Power on soft start reducing MOSFET Vds
PWM control IC optimized for high performance, low standby power and cost effective offline flyback converter applications. At normal load condition, it operates in fixed frequency mode. When the loading goes low, it operates in PFM mode for high power conversion stress
- Multi-Mode Operation
120K clamping frequency @Peak load in low line voltage 65KHz fixed frequency @ Heavy Load in low efficiency. When the load is very small, the IC line voltage operates in ‘Extended Burst Mode’ to minimize the
Burst Mode @ Light Load & No Load standby power loss. As a result, high conversion
- Frequency shuffling for EMI efficiency can be achieved in the whole loading
- Extended burst mode control for improved range. VCC low startup current and low operating current contribute to a reliable power on startup and low efficiency and low standby power design
- Audio noise free...
