appliances

Description

The device is a high voltage converter, which

smartly integrates an 800 V rugged power

MOSFET with a quasi-resonant current mode

PWM control. This IC meets severe energy

saving standards as it has very low consumption

and operates in burst mode under light load

conditions.

The device features the brown-out enabling the

IC to set the switch-off and switch-on threshold

independently one of each other. The quasi-

resonant operation reduces the level of EMI and

the quantity of components in the application.

The quasi-resonant operation reduces the

switching losses and improves power conversion

efficiency. The device features high level

protections such as: output overvoltage, short-

circuit and thermal shutdown with hysteresis.

After the removal of a fault condition, the IC is

automatically restarted.
