VIPer0P
Datasheet
Zero-power off-line high voltage converter
Features
•
•
•
Smart stand-by architecture using the zero-power mode (ZPM)
ZPM management by MCU easily realizable
800 V avalanche-rugged power MOSFET allowing ultra wide VAC input range to
be covered
SO16 narrow
•
•
•
•
•
•
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 to remove the auxiliary winding or bias components
Minimized system input power consumption:
–
–
–
Less than 4 mW @ 230 VAC in ZPM
Less than 10 mW @ 230 VAC in no-load condition
Less than 400 mW @ 230 VAC with 250 mW load
•
Jittered switching frequency reduces the EMI filter cost
–
–
60 kHz ± 7% (type L)
120 kHz ± 7% (type H)
•
•
Embedded E/A with 1.2 V reference and separate ground for easy negative
voltage setting
Protections with automatic restart: overload/short circuit (OLP), max. duty cycle
counter, VCC clamp
•
•
•
Pulse-skip protection to prevent flux-runaway
Embedded thermal shutdown
