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 EMI
Enhanced Safety and Reliability Features
Accurate hysteretic thermal shutdown protection with automatic
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.

Table 1. Output Power Table.
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).
3. Packages: P: DIP-8C, D: SO-8C, K: eSOP-12B. See Part Ordering Information.
