PKS603-607
PeakSwitchFamily
Enhanced, Energy-Efficient, Off-Line Switcher
IC With Super Peak Power Performance
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
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 – 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
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.

Pin Functional Description
DRAIN (D) Pin:
The power MOSFET drain connection provides internal
operating current for both startup and steady-state operation.
BYPASS (BP) Pin:
A0.33 µF external bypass capacitor for the internally generated
5.8 V supply is connected to this pin. In typical applications,
this pin must be externally supplied via a bias winding.
ENABLE/UNDER-VOLTAGE (EN/UV) Pin:
This pin has dual functions: enable input and line under-voltage
sense. During normal operation, switching of the power MOSFET
is controlled by this pin. MOSFET switching is disabled when a
current greater than 240 µA is drawn from this pin. This pin may
also sense line under-voltage conditions through either an
external resistor connected to the DC line voltage or an AC
sense circuit.
SOURCE (S) Pin:
This is the MOSFET source connection for high voltage return
and control circuit common.
