TNY253/254/255 TinySwitch™ Family
Energy Efficient, Low Power Off-line Switchers
Product Highlights
Lowest Cost, Low Power Switcher Solution Lower cost than RCC, discrete PWM and other integrat-
ed/hybrid solutions Cost effective replacement for bulky linear adapters Lowest component count Simple ON/OFF control – no loop compensation devices No bias winding – simpler, lower cost transformer Allows simple RC type EMI filter for up to 2 W from
universal input or 4 W from 115 VAC input
Extremely Energy Efficient Consumes only 30/60 mW at 115/230 VAC with no load Meets Blue Angel, Energy Star, Energy 2000 and 200 mW
European cell phone requirements for standby Saves $1 to $4 per year in energy costs (at $0.12/kWHr)
compared to bulky linear adapters Ideal for cellular phone chargers, standby power supplies for
PC, TV and VCR, utility meters, and cordless phones.
High Performance at Low Cost High-voltage powered – ideal for charger applications Very high loop bandwidth provides excellent transient
response and fast turn on with practically no overshoot Current limit operation rejects line frequency ripple Glitch free output when input is removed Built-in current limit and thermal protection 44 kHz operation (TNY253/4) with snubber clamp
reduces EMI and video noise in TVs and VCRs Operates with optocoupler or bias winding feedback
