STEVAL-ISA033V1

STEVAL-ISA033V1 55 W flyback SMPS demonstration board for alarm system based on the L5991 and STP12NK80Z Data Brief Features ■ Input voltage: – Vin: 88 - 300 Vac (f: 50-60 Hz) ■ Output voltages: – Vout1 = 13.8 V, Iout1 = 3 A – Vout2 = 25 V, Iout2= 200 mA – Vout3 = 3.8 V, Iout3 = 350 mA (1.9 A peak) ■ Output signals: – AC input check – Low battery check ) s ( ct u d o r P e let STEVAL-ISA033V1 Description o s b This demonstration board is a multi-output SMPS which can be used to supply an alarm system. O ) The circuit is composed of an AC-DC single output converter with an approximate power capability of 60 W, while the other outputs are obtained by means of DC-DC converters. The power supply also integrates a battery charger circuit in order to charge a standard SLA 12 V battery. s ( t c u d o r P e t e l o s b O June 2008 Rev 1 For further information contact your local STMicroelectronics sales office. 1/6 www.st.com 6 N C O N2 N T C 1 6 o hm t 100n 400V FUS E t 2 1 F1 R2 15k R20 1N4148 D5 L1 15m H 3 270n C14 R4 15k 1 2 3 4 5 6 7 8 C10 680n Q2 BC337 n.c n .c .
