VIPer20A-E
SMPS primary I.C.
General features
Adjustable switching frequency up to 200 kHz
Current mode control
Soft start and shutdown control
Automatic burst mode operation in stand-by
condition able to meet “blue angel” norm (<1w
total power consumption)
Internally trimmed zener reference
Undervoltage lock-out with hysteresis
Integrated start-up supply
Over-temperature protection
Low stand-by current
Adjustable current limitation
Description
All the devices are made using VIPower M0
Technology, combines on the same silicon chip a
state-of-the-art PWM circuit together with an
optimized, high voltage, Vertical Power MOSFET
(700V/ 0.5A).
Typical applications cover offline power supplies
with a secondary power capability of 10W in wide
range condition and 20W in single range or with
doubler configuration. It is compatible from both
primary or secondary regulation loop despite
using around 50% less components when
compared with a discrete solution. Burst mode
operation is an additional feature of this device,
offering the ability to operate in stand-by mode
without extra components.
