VIPerPlus family: peak power high-voltage converter
Datasheet
-
production data
Output overvoltage protection with tight
tolerance and digital noise filter
Soft-start reduces the stress during startup and
increases IC lifetime
Automatic restart after a fault condition
Thermal shutdown increases system reliability
and IC lifetime
Applications
Figure 1. Typical application
Auxiliary power supply for consumer and home
equipment
Power supply for energy meters and data
concentrators
Adapters
Description
The device is a high-voltage converter that
smartly integrates an 800 V rugged power
MOSFET with PWM current-mode control. The
power MOSFET allows a very high input V
ac
to be
applied, just limited from its breakdown voltage.
This IC is capable of meeting more stringent
energy-saving standards as it has very low
consumption and operates in burst mode under
light load.
The device features an adjustable extra power
timer (EPT) that enables the IC to sustain
overload conditions for a few seconds.
The integrated HV startup, sense FET and
oscillator with jitter allow the advantage of using
minimal components in the application.
The device features high-level protections like
dual-level OCP, output overvoltage, short-circuit,
and thermal shutdown with hysteresis. After the
removal of a fault condition, the IC is
automatically restarted.
Features
800 V avalanche-rugged power MOSFET
allowing ultra wide range input V
ac
to be
achieved
Embedded HV start-up and sense FET
PWM current-mode controller
OCP with selectable threshold (I
Dlim
) and 2
nd
OCP with higher value (I
DMAX
) to protect the IC
from transformer saturation or short-circuit of
the secondary diode
30 mW no-load consumption at 230 V
ac
Two operating frequencies:
– 60 kHz (L type) or 115 kHz (H type)
Jittered frequency reduces the EMI
Extra power timer (EPT) blanks the overload
current for few seconds
