Description
The TNY247PN is an electronic component model in the IC Chips product category. It is part of the TinySwitch family, which offers a breakthrough design for low-cost and high-efficiency off-line switcher solutions in the 0 to 10 W range. This model integrates a 700 V power MOSFET, oscillator, high voltage switched current source, current limit, and thermal shutdown circuitry. Unlike other solutions, the TNY247PN starts up and runs on power derived from the DRAIN voltage, eliminating the need for a transformer bias winding and associated circuitry. It consumes only about 80 mW at no load, resulting in energy efficiency. With a simple ON/OFF control scheme, loop compensation devices are not required.
Specifications and features
- Lowest cost, low power switcher solution
- Lower cost than RCC, discrete PWM, and other integrated/hybrid solutions
- Cost-effective replacement for bulky linear adapters
- Low 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 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, 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
Application Scenarios
The TNY247PN is suitable for a wide range of applications such as cellular phone chargers, standby power supplies for PC, TV, and VCR, utility meters, and cordless phones. Its low energy consumption makes it compliant with energy efficiency standards such as Blue Angel, Energy Star, Energy 2000, and 200mW European cell phone requirements for standby power. It is an ideal choice for customers looking for a cost-effective, high-performance solution.
