PKS604P Overview
PeakSwitch is designed to address applications with high peakto-continuous power ratio demands. The very high switching frequency during peak power loads and excellent load transient response reduce system cost as well as ponent count and size. PeakSwitch incorporates a 700 V power MOSFET, oscillator, high voltage switched current source for startup, current limit, and thermal shutd.
PKS604P Key Features
- 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 p
- Two external ponents 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 plete system level overload protection and elimina
- Simple ON/OFF control
