RAA223183中文资料1000V Off-Line Flyback Regulator数据手册Renesas规格书

描述 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.

特性 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 IEC61000-4-5 with cap-saving operation
