www.DataSheet4U.com IRISMPS5 IRISMPS5 DEMO BOARD USER GUIDE INTRODUCTION : The IRISMPS5 is an open frame 90W Flyback power supply unit (psu) using the IRIS4015 Integrated switcher. This demo board aims to show the capability of the IRIS4015 to handle the upper level of flyback topology power range, without the strict standby power requirement. It works with the wide range of input AC voltage (universal) and has a single output of +15V / 6amp. Switching frequency varies according to line and load condition. It operates in quasiresonant mode ( switching current is in critically discontinuous mode) at rated capacity. This switching technique enables the internal power mosfet of IRIS4015 to switch at variable frequency with minimum switching loss. SPECIFICATION DATA 1.
