Description

*1'

;ŽƉƚŝŽŶĂůͿ

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 V_acto be

applied, just limited from its breakdown voltage.

This IC is capable of meeting more stringent

energy-saving standards as it has very low

consumption and operates in burst mode under

light load.

Features

• 800 V avalanche-rugged power MOSFET

allowing ultra wide range input V_acto be

achieved

The device features an adjustable extra power

timer (EPT) that enables the IC to sustain

overload conditions for a few seconds.

• 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

The integrated HV startup, sense FET and

oscillator with jitter allow the advantage of using

minimal components in the application.

The device features high-level protections like

dual-level OCP, output overvoltage, short-circuit,

and thermal shutdown with hysteresis. After the

removal of a fault condition, the IC is

• 30 mW no-load consumption at 230 V_ac

• Two operating frequencies:

– 60 kHz (L type) or 115 kHz (H type)

automatically restarted.

• Jittered frequency reduces the EMI

• Extra power timer (EPT) blanks the overload

current for few seconds
