VIPer0P

VIPer0P Datasheet Zero-power off-line high voltage converter SO16 narrow Product status link VIPer0P 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 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 Built in soft start for improved system reliability Applications SMPS for home appliances, home automation, industrial, lighting and consumers Figure 1.
