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
