PKS603-607
PeakSwitch® Family
Enhanced, Energy-Efficient, Off-Line Switcher
IC With Super Peak Power Performance
Product Highlights
EcoSmart娉 Extremely Energy-Efficient
⢠Standby output power â¥0.6 W for 1 W input (high line)
⢠Sleep mode power â¥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
PeakSwitch 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 â no loop compensation needed
⢠Very low component count â 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
Description
PeakSwitch is 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.
PeakSwitch incorporates a 700 V power MOSFET, oscillator,
high voltage switched current source for startup, current limit,

and thermal shutdown onto a monolithic device. In addition,
these devices incorporate auto-restart, line under-voltage sense
and frequency jittering. An innovative design minimizes audio
frequency components in the simple ON/OFF control scheme
to practically eliminate audible noise with standard varnished
transformer construction.
