TNY5074V

Integrated off-Line switcher with EcoSmart Technology, unleashing up to 175 W output and achieves 92% efficiency in classic flyback architecture

Applications

Product Details

The TinySwitch-5 IC is an integrated switched mode power supply IC that monitors an analog feedback current at the control input to modulate the variable frequency variable current control.

The TinySwitch-5 flyback controller can operate in continuous conduction mode (CCM) or discontinuous conduction mode (DCM). The controller consists of a frequency jitter oscillator, a current limit controller, 5 V regulator on the BYPASS pin, BYPASS undervoltage and overvoltage detection circuit, an input line sensing circuit, current limit selection circuitry, over-temperature protection, leading edge blanking, and a silicon MOSFET power switch.

Product Highlights

Highly Integrated, Compact Footprint

  • Robust 725 V silicon MOSFET provides excellent surge withstand
  • Switching frequency up to 150 kHz minimizes transformer size

EcoSmart™ – Energy Efficient

  • High efficiency across the load range
  • Less than 30 mW no-load power at 230 VAC including line sense
  • Up to 210 mW output power for 300 mW input (230 VAC)
  • Lossless primary current sensing

Reduced Part Count, Design Flexibility

  • Frequency jitter reduces EMI filter size
  • Integrated soft-start minimizes start-up stress
  • Adjustable switching frequency
  • ILIM selection without extra components

Extensive Protection

  • Auto-restart limits power delivery to <3% during overload faults
  • Output short-circuit, overload and overvoltage protection
  • Line undervoltage (UV) detection prevents turn-off glitching
  • Simple, fast AC reset
  • Line overvoltage (OV) shutdown increases protection from line surge
  • Accurate thermal shutdown with large hysteresis (OTP)

Applications

  • Auxiliary, standby and bias power supplies for appliances, and consumer products
  • Utility meter, smart grid and industrial power supplies
