Order codes Package DIP-7 SO16 narrow Packaging Tube Tape and reel Doc ID 15585 Rev 4 1/40īlock diagram. Typical topologyĪdapters for PDA, camcorders, shavers, cellular phones, cordless phones, videogames Auxiliary power supply for LCD/PDP TV, monitors, audio systems, computer, industrial systems, LED driver, No el-cap LED driver, utility power meter SMPS for set-top boxes, DVD players and recorders, white goods The high voltage start-up circuit is embedded in the device. Brownout and brown-in function protects the switch mode power supply when the rectified input voltage level is below the normal minimum level specified for the system. The quasiresonant feature reduces EMI filter cost. Burst mode operation and device very low consumption helps to meet the standby energy saving regulations. The device is an off-line converter with 800 V rugged power section, a PWM control, double levels of overcurrent protection, overvoltage and overload protections, hysteretic thermal protection, soft-start and safe auto-restart after any fault condition removal. Similar parts: BM2P054, BM2P033, BM2P093, BM2P034, BM2P094, BM2P014, BM2P053Ĩ00 V avalanche rugged power section Quasi-resonant (QR) control for valley switching operation Standby power at 265 Vac Limiting current with adjustable set point Adjustable and accurate overvoltage protection On-board soft-start Safe auto-restart after a fault condition Hysteretic thermal shutdown Constant-current operation with an adjustable set point allows these STMicroelectronics high-voltage converters to cover all the mains voltages in SMPS design up to 30 W. The VIPerPlus family also represents the easiest solution to comply with the Blue Angel and Energy Star eco norms, with extremely low (less than 50 mW) total power consumption from the mains when the system is in standby mode. The STMicroelectronics VIPerPlus high-voltage converter offers benefits such as optimized current-mode control and comprehensive built-in protection circuits. The result is truly innovative AC-DC conversion that ensures efficiency, robustness, and saved costs. The STMicroelectronics VIPerPlus high-voltage converter series combines the innovative 800 V avalanche-rugged SuperMESH™ power MOSFET with state-of-the-art PWM circuitry.
