VIPER01

VIPer01 Energy saving off-line high voltage converter Datasheet - production data Figure 1: Basic application schematic 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  Jittered switching frequency reduces the EMI filter cost:  30 kHz ± 7% (type X)  60 kHz ± 7% (type L)  120 kHz ± 7% (type H)  Embedded E/A with 1.2 V reference  Protections with automatic restart: overload/short-circuit (OLP), line or output OVP, max. duty cycle counter, VCC clamp  Pulse-skip protection to prevent flux-runaway  Embedded thermal shutdown  Bui...
