TNY254GN Product Details


The TinySwitch family uses a breakthrough design to provide the lowest cost, high efficiency, off-line switcher solution in the 0 to 10 W range. These devices integrate a 700 V power MOSFET, oscillator, high-voltage switched current source, current limit and thermal shutdown circuitry. They start-up and run on power derived from the DRAIN voltage, eliminating the need for a transformer bias winding and the associated circuitry. And yet, they consume only about 80 mW at no load, from 265 VAC input. A simple ON/OFF control scheme also eliminates the need for loop compensation.

Product Highlights 

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 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
