TNY288PG IC - Power Integrations Off Line Switcher IC

TNY288PG is also belongs to TinySwitch-4 Family from the manufacturer "Power Integrations". It is Energy-Efficient, Off-Line Switcher with Line Compensated Overload Power. It comes with following features:-

• Lowest System Cost with Enhanced Flexibility
  • 725 V rated MOSFET
  • Increases BV de-rating margin
  • Line compensated overload power – no additional components
  • Dramatically reduces max overload variation over universal input voltage range
  • ±5% turn on UV threshold: line voltage sense with single external resistor
  • Simple ON/OFF control, no loop compensation needed
  • Selectable current limit through BP/M capacitor value
  • Higher current limit extends peak power or, in open frame applications, maximum continuous power
  • Lower current limit improves efficiency in enclosed adapters/ chargers
  • Allows optimum TinySwitchâ„¢-4 choice by swapping devices with no other circuit redesign
  • Tight I2 f parameter tolerance reduces system cost
    • Maximizes MOSFET and magnetics utilization
  • 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 heat sinking to the PCB
  • SOURCE pins are electrically quiet for low EMI
• Enhanced Safety and Reliability Features
  • 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
  • Fast AC reset with optional UV external resistor
  • 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

Application:-

• PC Standby and other auxiliary supplies
• DVD/PVR and other low power set top decoders
• Supplies for appliances, industrial systems, metering, etc
• Chargers/adapters for cell/cordless phones, PDAs, digital cameras, MP3/portable audio, shavers, etc.
