Description
TNY174DN is an electronic component model in the IC Chips category. It is part of the TinySwitch-LT family and incorporates a 650 V power MOSFET, oscillator, high voltage switched current source, current limit (user selectable) and thermal shutdown circuitry. This IC offers a low system cost and extended power capability, making it a flexible solution for various applications.
Specifications and features
- 650 V rating optimized for non-active PFC applications
- Simple ON/OFF control, no loop compensation needed
- Selectable current limit through BP/M capacitor value
- Tight I2f parameter tolerance reduces system cost
- 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 heatsinking to the PCB
- SOURCE pins are electrically quiet for low EMI
- 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
- 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
- Easily meets all global energy efficiency regulations
- No-load <150 mW at 265 VAC without bias winding, <50 mW with bias winding
- ON/OFF control provides constant efficiency down to very light loads – ideal for mandatory CEC regulations
Application Scenarios
- Chargers/adapters for cell/cordless phones, PDAs, digital cameras, MP3/portable audio, shavers, etc.
- DVD/PVR and other low power set top decoders
- Supplies for appliances, industrial systems, metering, etc.
