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.

IRISMPS5 PHYSICAL LAYOUT
The board layout of the IRISMPS5 Demo board is shown in Figure 2. The PCB is a double-sided FR4 type ( 2oz. copper thickness). The input of the primary section is consist of the AC input connector, fuse and EMI filter section which are located at the right side of the board, arranged in a straight forward direction. Most parts of the primary section ( high voltage area ) are surrounded by the primary heat sink to which the IRIS4015 integrated switcher is attached with insulation pad. Primary section also includes the bridge rectifier DB1 and primary bulk cap/s (C5 or C5A//C5B) and primary side and bias winding of the power transformer. The major parts in the secondary section are the DC output connector, pi-filter, precision reference voltage IC U2, secondary heat sink to which the output rectifier is attached with thermal grease. The output connector is at the leftmost part of the board. The output is filtered using a pi-filter consist of low impedance e-caps C13A - C ,inductor L3 and e-cap C15. A ceramic capacitor C16 is located at the backside of the board. This c-cap is positioned nearest at output connector pads to minimize switching noise.
