描述 Description

The RAA223182 is an off-line Flyback regulator with a 1000V integrated MOSFET, designed for high input voltage applications such as 3-phase electric meter power supplies and other generally isolated power supplies. The RAA223182 can deliver up to 11W from the universal 3-phase input voltage.

特性 Features

• Flyback regulator with 1000V 9Ω MOSFET
• Frequency doubling for heavy load operation (21W and above), for a programmable duration (maximum time depends on thermal capability)
• Fault-tolerant input overvoltage protection
• 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).
