Description

PeakSwitchis designed to address applications with high peak to-continuous power ratio demands. The very high switching

frequency during peak power loads and excellent load transient response reduce system cost as well as component count and size.

Product Highlights

EcoSmart? – Extremely Energy-Efficient

? Standby output power ≥0.6 W for 1 W input (high line)

? Sleep mode power ≥2.4 W at 3 W input (high line)

? No-load consumption <200 mW at 265 VAC input

? Surpasses California Energy Commission (CEC), ENERGY STAR, and EU requirements

PeakSwitchFeatures Reduce System Cost

? Delivers peak power of up to 3 times maximum continuous output power

? 277 kHz operation during peak power significantly reduces transformer size

? Programmable smart AC line sensing provides latching shutdown during short circuit, overload and open loop faults and prevents power ON/OFF glitches during power down or brownout

? Two external components reset latch on AC removal

? Adaptive switching cycle on-time extension increases low line peak output power, minimizing bulk capacitor size

? Adaptive current limit reduces output overload power

? Frequency jittering reduces EMI filter cost

? Tight I2f tolerances and negligible temperature variation of key parameters ease design and lower cost

? Accurate hysteretic thermal shutdown with automatic recovery provides complete system level overload protection and eliminates need for manual reset

Better System Cost/Performance over RCC & Discrete

? Simple ON/OFF control – no loop compensation needed

? Very low component count – higher reliability and single side printed circuit board

? High bandwidth provides fast turn on with no overshoot and excellent transient load response

? Peak current limit operation rejects line frequency ripple

? Built-in current limit and hysteretic thermal protection

Applications

? Inkjet printer

? Data storage, audio amplifier, DC motor drives
