Power Integrations PKS604
Off-Line Switcher
FEATURES
Reduce System Cost● Delivers peak power of up to three 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 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 co...
