overload/short-circuit (OLP), line or output
OVP, max. duty cycle counter, VCC clamp
 Pulse-skip protection to prevent
flux-runaway
 Embedded thermal shutdown
 Built-in soft-start for improved system
reliability
Applications
 Low power SMPS for home appliances,
building and home control, small industrial,
consumers, lighting, motion control
 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.
