Power Integrations Announces New PeakSwitch Reference Design Kit (RDK-203) to Meet Latest ENERGY STAR(R) Standby Power Specification for Audio-Video Equipment Consumers
The new PeakSwitch Reference Design Kit (RDK-203) is a dual-rail power supply with high loop bandwidth and peak power for home theater systems with up to 650 watts audio power rating. The new reference design enables developers to easily meet new and emerging standby power usage regulations for consumer audio-video equipment. RDK-203 is based on Power Integrations’PKS607YN, a member of the PeakSwitchproductfamily. With a response time of 40 microseconds, amplifiers powered by PeakSwitch-based power supplies can keep up with high-crest-factor, high-frequency audio signals common in high quality digital music and DVD movie soundtracks…
Typical Power Application
Description:
|
advertisement |
- 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
Output Power Table
Notes :
- Typical continuous power in a non-ventilated enclosed adapter measured at +50 °C ambient.
- Typical peak power for a period of 100 ms and a duty cycle of 10% in a non-ventilated enclosed adapter measured at +50 °C (see Key Applications section for details).
