Overview
Description
The RAA223183 is an off-line Flyback regulator with a 1000V integrated MOSFET, designed for high-reliability application of single-phase and 3-phase smart meter power supplies and other generally isolated power supplies. The RAA223183 can deliver up to 7W power from the single-phase and 11W from 3-phase universal inputs.
Features
- Flyback regulator with 1000V 9Ω MOSFET
- Single 400V bulk capacitor for single-phase input up to 460VAC
- Frequency doubling for heavy load operation (up to 15W in single-phase and 21W and above in 3-phase), with programmable duration (maximum time depends on thermal capability)
- Valley switching to reduce switching losses
- Programmable constant frequency PWM operation
- Burst mode operation at light load
- Protection features: Short-circuit protection (SCP), overload protection (OLP), input undervoltage lockout (VinUV), Input OVP, VCC overvoltage protection (VccOV), VCC undervoltage lockout (VccUV) and over-temperature protection (OTP).
- 4KV surge compliance per IEC 61000-4-5 with cap-saving operation
