Typical Standby Application
Description:
- Energy-efficient replacement for regulated linear transformer and discrete power supply designs
- Universal input range allows worldwide operation
- Self-biased supply – saves transformer auxiliary winding and associated bias supply components
- Built-in current limit and hysteretic thermal shutdown protection
- Fully integrated auto-restart for short-circuit and open loop protection
- Tight tolerances and negligible temperature variation on key parameters eases design and lowers cost
- High maximum switching frequency allows very low
flux density transformer designs, practically eliminating audible noise
- Frequency jittering greatly reduces EMI
- Packages with large creepage to high voltage pin
- Lowest component count switcher solution
Applications:
- Chargers for cell/cordless phones, PDAs, digital cameras, MP3/portable audio devices, shavers etc.
- Standby and auxiliary supplies
