The VIPer17 offline switched-mode converter integrates an 800 V avalanche-rugged MOSFET, as well as numerous features to save external components and ensure efficient operation during standby mode. Constant-current operation with an adjustable set point allows use with all mains voltages using SMPS (switched-mode power supply) designs up to 12 W.
The VIPer12A-E
and VIPer22A-E
combine a dedicated current-mode PWM controller with high-voltage
power MOSFET on the same chip. Typical applications cover offline
power supplies for battery chargers, adapters, standby power supplies
for TV and monitors, and auxiliary supplies for motor control, for
instance. The secondary feedback using an optocoupler driven by
a TSM device allows regulation on both the voltage output and current,
giving the well-known rectangular (U-I) output characteristic needed
for battery chargers.
The VIPer53-E
and VIPer53E-E
combine an enhanced current-mode PWM controller with a high-voltage
MDMesh power MOSFET in the same package. Typical applications cover
offline power supplies with secondary power capability ranging up
to 30 W in wide-range input voltage or 50 W in single European voltage
range in a DIP-8 package, and 40 W in wide-range input voltage or
65 W in single European voltage range in a PowerSo-10 package. The
VIPer53-E and VIPer53E-E offer a special feature to handle low-load
condition. This consists in reducing the switching frequency by
going into burst mode. |

ST's VIPer series of offline switch-mode power supplies
combines an optimized, high-voltage, vertical power MOSFET
with state-of-the-art PWM circuitry. The result is truly
innovative AC-to-DC conversion that is simpler, quicker
and - with component count halved - less expensive. In
addition to benefits such as optimized current mode control
and comprehensive built-in protection circuits, the VIPer
family represents the easiest solution to comply with
the Blue Angel and Energy Star eco norms, with extremely
low total power consumption from the mains when the system
is in standby mode.
