The new VIPer53E includes a PWM driver, an

MDmesh MOSFET, a start-up high voltage current

source and several on-chip protection circuits.

The VIPer53E is an alternative choice to the VIPer53

when only the secondary regulation is required in

a power supply. Like the standard VIPer53, the new

version is housed in surface mounting DIP-8 and

PowerSO-10 packages.

The higher V

voltage range brings flexibility in

designing the transformer. In fact in secondary

regulation VIPer53E V

voltage extends from 9V

to 18V, while in the VIPer53 it goes from 9V to 14.5V

and this wide voltage range can follow fast load

variations. The extended V

is implemented by

eliminating an internal error amplifier.

Thanks to the MDmesh MOSFET with a breakdown

voltage of 620V, an R

DS(on)

of 1Ω at 25°C and a

typical handling output power of 40W for a 85 to

265Vac voltage mains. For this level of power the

device does not require a heat-sink.

The total power consumption of the converter is less

than 0.5W for the system when working in stand-by

mode. This means power supply designers can easily

meet the Blue Angel Eco or Energy Star Program.

Automatic burst mode for very low consumption

in stand-by conditions (less than 500mW);

Integrated high voltage start-up current source;

Overload and short circuit control;

Over-voltage protection at 18V;

Over-temperature shutdown;

Under-voltage protection;

Current mode control with adjustable drain current

limitation;

Externally set switching frequency, up to 300kHz.

Although the main application of VIPer53E is in

AC/DC converters for consumer equipment such

as set-top boxes, DVDs, VCRs, it can also be used

for stand-by power supplies for servers or in home

appliances where a very efficient AC/DC power

supply in buck topology is needed.
