TNY256
TinySwitch® Plus
Energy Efficient, Low Power Off-line Switcher
Product Highlights
TinySwitch Plus Features Extended power range Fully integrated auto-restart reduces short circuit current Line under-
voltage sense eliminates turn-off glitches Frequency jittering dramatically reduces EMI (5 to 10 dB) TO-220 package option
Lowest Cost, Low Power Switcher Solution Lower cost than RCC, discrete PWM and other
integrated/hybrid solutions Cost effective replacement for bulky linear adapters Lowest component count Simple ON/OFF control – no loop compensation components No bias winding – simpler, lower cost transformer Designed to work with low cost external components
Extremely Energy Efficient Consumes only 30/60 mW at 115/230 VAC with no load Meets Blue Angel, Energy Star, Energy 2000 and
200mW 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 and adapters
High Performance at Low Cost High
voltage powered – ideal for charger applications High bandwidth provides fast turn on with no overshoot Current limit operation rejects line frequency ripple Built-in current limit and thermal protection
Description
