TNY290PG Datasheet, PDF (1/26 Pages) Power Integrations, Inc. – Energy-Efficient, Off-Line Switcher With Line Compensated Overload Power
TNY284-290
TinySwitch™-4 Family
Energy-Efficient, Off-Line Switcher With
Line Compensated Overload Power
Product Highlights
Lowest System Cost with Enhanced Flexibility
• 725 V rated MOSFET
• Increases BV de-rating margin
• Line compensated overload power – no additional components
• Dramatically reduces max overload variation over universal
input voltage range
• ±5% turn on UV threshold: line voltage sense with single
external resistor
• Simple ON/OFF control, no loop compensation needed
• Selectable current limit through BP/M capacitor value
• Higher current limit extends peak power or, in open frame
applications, maximum continuous power
• Lower current limit improves efficiency in enclosed
adapters/chargers
• Allows optimum TinySwitch-4 choice by swapping devices
with no other circuit redesign
• Tight I2f parameter tolerance reduces system cost
• Maximizes MOSFET and magnetics utilization
• ON-time extension – extends low-line regulation range/hold-up
time to reduce input bulk capacitance
• Self-biased: no bias winding or bias components
• Frequency jittering reduces EMI filter costs
• Pin-out simplifies heat sinking to the PCB
• SOURCE pins are electrically quiet for low EMII
Enhanced Safety and Reliability Features
• Accurate hysteretic thermal shutdown protection with auto-
matic recovery eliminates need for manual reset
• Auto-restart delivers <3% of maximum power in short-circuit
and open loop fault conditions
• Output overvoltage shutdown with optional Zener
• Fast AC reset with optional UV external resistor
• Very low component count enhances reliability and enables
single-sided printed circuit board layout
• High bandwidth provides fast turn-on with no overshoot and
excellent transient load response
• Extended creepage between DRAIN and all other pins improves
field reliability
EcoSmart™– Extremely Energy Efficient
• Easily meets all global energy efficiency regulations
• No-load <30 mW with bias winding, <150 mW at 265 VAC
without bias winding
• ON/OFF control provides constant efficiency down to very light
loads – ideal for mandatory CEC regulations and EuP standby
requirements
Applications
• PC Standby and other auxiliary supplies
• DVD/PVR and other low power set top decoders
• Supplies for appliances, industrial systems, metering, etc
• Chargers/adapters for cell/cordless phones, PDAs, digital
cameras, MP3/portable audio, shavers, etc.

Notes:
1. Minimum continuous power in a typical non-ventilated enclosed adapter
measured at +50 °C ambient. Use of an external heat sink will increase power
capability.
2. Minimum peak power capability in any design or minimum continuous power in
an open frame design (see Key Applications Considerations).
