PeakSwitch
Enhanced, Energy-Efficient, Off-Line Switcher IC with Super Peak Power Performance
Typical Peak Power Application
Description:
- Simple ON/OFF control, no loop compensation needed
- Delivers peak power of up to 3 times maximum continuous output power
- 277 kHz operation during peak power significantly reduces transformer size
- Tight I2f tolerances and negligible temperature variation of key parameters ease design and lower cost
- Adaptive on-time extension increases low line peak output power and minimizes bulk capacitor size
- Programmable smart AC line sensing provides latching shutdown during short circuit, overload and open loop faults and prevents ON/OFF glitches during power down or brownout
Applications:
Ideal for applications with large peak to continuous load ratio requirements
- Inkjet printer
- Data storage
- Audio amplifier
- DC motor drives
