VIPER012LS General 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.5 V / 200 mA high voltage buck-converter based o.75 W digitally controlled constant current LED d.Smart LED driver using 6LoWPAN Mesh network for .5 V, 0.85 A flyback converter using VIPer™.

Key Features

800 V avalanche-rugged power MOSFET allowing ultra wide V_AC 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 V_AC in no-load condition
- Less than 400 mW @ 230 V_AC 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, V_CC clamp
Pulse-skip protection to prevent flux-runaway
Embedded thermal shutdown
Built-in soft-start for improved system reliability

I have problems with the launch of devices. It turns out...To program enough power from the usb port of the computer, and to work the device needs a current of more than 0.5 a. i have the device went into a repetitive reboot. And after connecting an additional bp all earned.The camera itself is weak, but what can i do for such money, you can say, good...
