STEVAL-ISA096V1 STMicroelectronics

STEVAL-ISA096V1 Auxiliary power supply in buck-boost topology based on the Viper06 Data brief Features Input voltage: V : 85 ~ 264 Vrms f: 45 ~ 66 Hz in Output voltage: -12 Vdc 10%, 150 mA Standby < 30 mW at 264 Vac Short-circuit: protected PCB type and size: FR4 single-side 35 m, 32 x 90 mm Isolation: isolated 4 kV/8 mm EMI: according to EN55022 class B RoHS compliant Description The STEVAL-ISA096V1 is a switched mode power supply (SMPS) demonstration board. This non-isolated SMPS is designed in a buck-boost topology and is capable of delivering up to 2 W of output over a wide input voltage range. This board also offers the user the possibility of adapting the circuit to specific needs, thanks to an available free PCB area. The SMPS generates 12 V of nominal output voltage. The STEVAL-ISA096V1 demonstration board is based on the VIPer06, a monolithic converter that integrates an 800 V avalanche-rugged MOSFET and PWM controller in one package, offering a cost-effective and space-saving solution.
