VIPerPlus Truly innovative AC-DC conversion April 2009 www.st.com/viperAdvanced solutions for switch-mode power supplies STs VIPerPlus series of high-voltage converters combine In addition to benefits such as optimized current-mode (TM) the innovative avalanche-rugged SuperMESH power control and comprehensive built-in protection circuits, the MOSFET with state-of-the-art PWM circuitry. The result VIPerPlus family represents the easiest solution to comply is truly innovative AC-DC conversion that is efficient, with the Blue Angel and Energy Star eco norms, with simpler, quicker and - with component count halved - less extremely low total power consumption from the mains expensive. when the system is in standby mode. Key benefits QQ Ultra-low power-supply consumption: 30 mW standby at 265 V AC QQ Easily meets all energy efficiency regulations QQ Avalanche-rugged 800 V power section for high robustness and reduced clamp cost QQ Jittering feature reduces EMI filter cost and helps meet the EN550022 class B specifications QQ High efficiency using quasi-resonant version QQ No auxiliary winding costs for very low-power SMPS QQ Embedded advanced protection features for high PSU reliability QQ Easily compliant with the 2002/95/EC European directive QQ Extended pin creepage distance for safe operation in humid environments Power section: 800 V avalanche rugged R : 24 ohm R : 7 ohm DS(on) DS(on) Description I : DLIM I : 400 mA I : 700 mA DLIM DLIM 800 mA VIPER15 VIPER16 VIPER17 VIPER25 VIPER26 VIPER27 VIPER28 Fixed-frequency PWM current-mode controller Quasi-resonant PWM current-mode controller Fixed-frequency PWM current-mode controller with embedded error amplifier Limiting drain current with adjustable set point Fixed-frequency 60 kHz (L type) or 115 kHz (H type) with jittering Advanced standby management Automatic autorestart after fault Advanced overload and short circuit management Accurate overvoltage protection Open-loop failure detection Feed forward compensation On-board soft start up Hysteretic thermal shutdown Brown-out protection Extra power timer for peak power management Eliminates bias winding supply DIP7 (N type) DIP7 (N type) Packages SO16N (D type) SO16N (D type) Maximum output power with 230 V 10% up to 10 W up to 20 W AC Maximum output power with 85 to 265 V up to 6 W up to 12 W AC 2
