STEVAL-ISA060V1 STMicroelectronics

STEVAL-ISA060V1 6 W single output SMPS demonstration board based on the VIPER17 Data Brief Features Input voltage range Vin: 90 VRMS to 265 VRMS Output voltage V : 12 V out Max output current Iout: 500 mA Precision of output regulation V : 5% out LF High frequency output voltage ripple V : 50 mV out LF Description STEVAL-ISA060V1 This demonstration board is based on the new VIPER17 device and implements a standard Moreover internal thermal shutdown and an 800 V single-output isolated flyback converter operating avalanche rugged power MOSFET improve the at fixed frequency that can be 115 kHz or 60 kHz. robustness of all the system. The VIPER17 device integrates in the same If brownout and overvoltage protection are not package two components: an advanced PWM necessary, the number of external components is controller with built-in BCD6 technology and an further reduced. 800 V avalanche rugged vertical power MOSFET. It is very suitable for offline power conversion operating either with wide range input voltage (85 VAC - 270 VAC) up to 6 W or with single range input voltage (85 VAC - 132 VAC or 175 VAC - 265 VAC). With European range input voltage (175 VAC - 265 VAC) the device can handle up to 10 W of output power. The proposed solution has the advantage of using few external components compared to a discrete solution, providing several protections and very low standby consumption in no-load condition. The protections present on the device such as overload and output overvoltage protections, secondary winding short-circuit protection, hard transformer saturation and brownout protections improve the reliability and safety of the design. The frequency jittering, that is inside implemented, helps to meet the standards regarding electromagnetic disturbance.
