▪ 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).
