▪ 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
