TNY290PN AC/DC Switching Converter IC

TNY290PN IC - Power Integrations AC/DC Converter

TNY290 is TinySwitch-4 Family Energy-Efficient, Off-Line Switcher with Enhanced Flexibility and Extended Power Range. TNY290PN Switching Converter IC incorporates a 725 V power MOSFET, oscillator, high voltage switched current source, current limit (user selectable) and thermal shutdown circuitry. The IC family uses an ON/OFF control scheme and offers a design flexible solution with a low system cost and extended power capability.

TNY290PN AC/DC Switching Converter IC combines a high-voltage power MOSFET switch with a power supply controller in one device. Unlike conventional PWM (pulse width modulator) controllers, it uses a simple ON/OFF control to regulate the output voltage. The controller consists of an oscillator, enable circuit (sense and logic),current limit state machine, 5.85 V regulator, BYPASS/MULTIFUNCTION pin undervoltage, overvoltage circuit, and current limit selection circuitry, over-temperature protection, current limit circuit, leading edge blanking, and a 725 V power MOSFET. TinySwitch-4 incorporates additional circuitry for line undervoltage sense,auto-restart, adaptive switching cycle on-time extension, and frequency jitter. 

DNA Solutions deals in retail and bulk quantity. We have various values of AC/DC Switching converter IC's. Check our complete collection of AC DC converter and offline Switcher IC's.

Features of TNY290PN AC/DC Converter IC

  • 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 TinySwitch™-4 choice by swapping devices with no other circuit redesign
  • Tight I2f 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
