Low power adapters
Description
The device is a high voltage converter smartly
integrating an 800 V avalanche-rugged power
MOSFET with PWM current mode control. The
power MOSFET with 800 V breakdown voltage
allows the extended input voltage range to be
applied, as well as the size of the DRAIN snubber
circuit to be reduced. This IC meets the most
stringent energy-saving standards as it has very
low consumption and operates in pulse frequency
modulation under light load. The design of
flyback, buck and buck boost converters is
supported. The integrated HV startup, sense-
FET, error amplifier and oscillator with jitter allow
a complete application to be designed with the
minimum number of components.
Features
800 V avalanche-rugged power MOSFET
allowing ultra wide VAC input range to be
covered
Embedded HV startup and sense-FET
Current mode PWM controller
Drain current limit protection (OCP)
Wide supply voltage range: 4.5 V to 30 V
Self-supply option allows the auxiliary
winding or bias components to be removed
Minimized system input power consumption:
Less than 10 mW @ 230 VAC in no-load
condition
Less than 400 mW @ 230 VAC with
250 mW load
