ECCN EU	NEC
Packing Type	Tube
RoHs compliant	Ecopack2
Grade	Industrial
Package Name	SDIP 10

Description

The device is a high-voltage converter that smartly integrates an 800 V rugged power MOSFET with PWM current-mode control. The power MOSFET allows a very high input Vac to be applied, just limited from its breakdown voltage. This IC is capable of meeting more stringent energy-saving standards as it...

Key features
800 V avalanche-rugged power MOSFET allowing ultra wide range input V_ac to be achieved Embedded HV start-up and sense FET PWM current-mode controller OCP with selectable threshold (I_Dlim) and 2^nd OCP with higher value (I_DMAX) to protect the IC from transformer saturation or short-circuit of the secondary diode 30 mW no-load consumption at 230 V_ac Two operating frequencies: 60 kHz (L type) or 115 kHz (H type) Jittered frequency reduces the EMI Extra power timer (EPT) blanks the overload current for few seconds Output overvoltage protection with tight tolerance and digital noise filter Soft-start reduces the stress during startup and increases IC lifetime Automatic restart after a fault condition Thermal shutdown increases system reliability and IC lifetime
