VIPER01:VIPerPlus family: Low voltage energy saving fixed frequency high voltage converter
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.
Key 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
- Built-in soft-start for improved system reliability
