PeakSwitch

Family

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 I

f 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

Notes:

1. Typical continuous power in a non-ventilated enclosed adapter

measured at +50 °C ambient.

2. Typical peak power for a period of 100 ms and a duty cycle of

10% in a non-ventilated enclosed adapter measured at +50 °C

(see Key Applications section for details).

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.
