Applications
These ICs integrate a flyback controller and power switch in a single package, simplifying power-supply design for low-power chargers and adapters.
- The integrated power switch's voltage rating and Rdson must match the output power level to avoid under-derating
- Light-load/no-load efficiency affects compliance with standby-power efficiency limits
- Switching frequency and modulation mode (PWM/PFM switching, etc.) affect efficiency and EMI performance
- Higher protection integration reduces external component count but leaves less tuning flexibility
