High Voltage Switching Regulator for Offline SMPS
Obsolete
The NCP1028 offers a new solution targeting output power levels from a few watts up to 15W in a universal mains flyback application. Our proprietary high-voltage technology lets us include a power MOSFET together with a startup current source, all directly connected to the bulk capacitor. To prevent lethal runaway in low input voltage conditions, an adjustable brown-out circuitry blocks the activity until sufficient input level is reached.
Current-mode operation together with an adjustable ramp compensation offers superior performance in universal mains applications.
Protection wise, a timer detects an overload or a short-circuit and stops all operations, ensuring a safe auto-recovery, low duty cycle burst operation. An integrated, auto-recovery.
Finally, a great RDS(on) figure makes the circuit an excellent choice for standby/auxiliary offline power supplies or applications requiring higher output power levels.

Re-calculate Data
Data is based on the following assumptions.
Note: The temperature and confidence level may be adjusted to your requirements.
Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
