Description

The new VIPer17 device integrates in the same

package two components: an advanced PWM

controller built in BCD6 technology and an 800 V

avalanche rugged vertical power MOSFET. The

device is suitable for off line power converter

operating both, with wide range input voltage (85

VAC - 270 VAC) up to 7 W or with single range

input voltage (85 VAC - 132 VAC or 175 VAC - 265

VAC). With European range input voltage (175

VAC - 265 VAC) the device can handle up to 10 W

of output power. The proposed solution has the

advantage of using few external components

compared to a discrete solution, providing several

switch mode power supply's protections and very

low stand by consumption in no load condition.

VIPer17 device operates at fixed frequency that

can be 115 kHz or 60 kHz according to the part

number selected. Frequency jittering is

implemented and it helps to meet the standards

regarding electromagnetic disturbance The

several protections present on the device like:

overload, output short circuit, secondary winding

short, hard transformer saturation protection and

brown out protections, improve the reliability and

safety of the design. More over internal thermal

shut down and an 800 V avalanche rugged power

MOSFET improve the robustness of the system.

The present demonstration board is a standard

one output isolated fly-back converter that uses

all the protections above mentioned. If not

necessary brown out protection and over-voltage

protection could be not used reducing the number

of external comp furthermore.
