VIPER26LD Description
The VIPER26LD is a smart high voltage converter that integrates an 800 V avalanche-rugged power MOSFET with PWM current mode control. The VIPER26LD power MOSFET with 800 V breakdown voltage allows an extended input voltage range to be applied, as well as the size of the DRAIN snubber circuit to be reduced. This VIPER26LD IC meets the most stringent energy-saving standards with very low consumption and burst mode operation under light load.
VIPER26LD Features
800 V avalanche rugged power MOSFET allows a wide range of VAC input range to be covered
Embedded HV startup and sense-FET
The current mode PWM controller
Minimized system input power consumption:
– Less than 30 mW @ 230 VAC in no-load condition
– Less than 400 mW @ 230 VAC with 250 mW load
Limiting current with adjustable set point
Jittered switching frequency to reduce the EMI filter cost:
– 60 kHz ±4 kHz (L type)
– 115 kHz ±8 kHz (H type)
Embedded error amplifier
Hysteretic thermal shutdown
Built-in soft-start for improved system reliability
Protections with automatic restart: overload/short-circuit (OLP), feedback loop disconnection
VIPER26LD Applications
Auxiliary power supply for appliances
Power metering
LED drivers
SMPS for set-top boxes, DVD players, and recorders
