| HV9906DB4 Off-Line Current Source Controller Introduction The HV9906DB4 provides a constant current of 750mA. It contains all circuitry necessary to demonstrate the features of the HV9906 second order power supply controller. A power converter of the demo board consists of an input buck-boost stage and an output buck stage. The output voltage polarity is negative. Due to its unique quadratic input-tooutput DC voltage transfer ratio, the converter can operate directly off AC line to produce low-voltage output without need for electrolytic capacitors. The HV9906 is designed for optimally controlling this type of power converter or other types of two-stage multiconverters. The board is optimized for driving a 10V-20V, 750mA load. However, it may be modified to meet custom requirements (up to 80V or 1.5A). HV9906DB4 demo board features passive power factor correction to PF>0.95, open circuit protection and under voltage lockout. Specification Input Voltage Output Current Output Voltage Efficiency 80 to 135VAC, 60Hz 750mA 10% 20V Max 64% at Io=750mA, Vin=100VAC Board Layout and Connections TOP SIDE BOTTOM SIDE 80-135 VAC Radj (external) 80-135 VAC Radj (external) WARNING!!! Do not connect to scope ground or to the ground of other earth-grounded instruments. Doing so will short the AC line, resulting in damage to the circuit and/or instruments. Either use an isolation transformer on the AC line, use a differential probe, or use a floating, battery-powered instrument to make measurements. WARNING!!! No galvanic isolation. Dangerous voltages are present when connected to the AC mains. 1 07/23/2002 Supertex, Inc. 1235 Bordeaux Drive, Sunnyvale, CA 94089 TEL: (408) 744-0100 FAX: (408) 222-4895 www.supertex.com HV9906DB4 Instructions OUT, RTN Connect your LED to these terminals: negative to OUT, positive to RTN. E1, E2 Connect 80 to 135VAC, 60Hz line source to these terminals: line to E2, neutral to E1. The input is protected with a 0.5A fuse. DC, AGND Leave DC, AGND open if dimmer control is not required. Connect DC and AGND with an adjustable Resistor Radj can change the output current. The output current is: Iout = R1 + R 6 + R8 - R 7 //( R11 + Radj ) R 7 //( R11 + Radj ) R3 1V Setting Output Current (without Dimmer Control) Output current is preset to 750mA for this board. Output current can be re-programmed according to the following equation: Iout = R1 + R 6 + R8 - R 7 1V R 7 R3 Schematic Diagram Radj (external part) 2 07/23/2002 Supertex, Inc. 1235 Bordeaux Drive, Sunnyvale, CA 94089 TEL: (408) 744-0100 FAX: (408) 222-4895 www.supertex.com HV9906DB4 Parts List Item 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 REF B1 C1 C2 C3 C4 C5 C5A C6 C7 C8 C8A C9 D1 D2 D3 D4 D5 D6 F1 L1 L2 M1 M2 Q1 R1 R2 R3 R4 R5 R6 R7 R8 R9 R10 R11 Rth U1 Part Diode Bridge 0.22uFd, 250V, 10% 0.022uFd, 50V, 5% 0.1uFd, 16V, 5% 0.1uFd, 16V, 5% 0.01uFd, 50V 0.1uFd, 16V, 5% 0.1uFd, 16V, 5% 1500pFd, X7R, 50V Ultra Fast, 400V, 1A Ultra Fast, 400V, 1A Ultra Fast, 200V, 1A 1N4148 Zener, 4.7V TVS, 1.5KW 54V 1/2A, Slow Blow 100uH 100uH MOSFET, 400V MOSFET, 350V BJT, PNP 15K ohm, 1% 1.0M Ohm, 1% 0.47 ohm, 1% 10.0M Ohm, 1% 84.6K ohm, 1% 105K ohm, 1% 100K ohm, 1% 15K ohm, 1% 1.4M Ohm, 1% 10.0 Ohm, 1% 100K Ohm, 1% 0 Ohm PWM/PFM IC Package Manufacturer Panasonic Pen Film Panasonic Pen Film Panasonic Pen Film Panasonic PPS Film Panasonic PPS Film Panasonic PPS Film Kemet or equivalent Panasonic or equivalent Panasonic PPS Film Panasonic PPS Film Panasonic or equivalent On Semi or equivalent On Semi or equivalent On Semi or equivalent On Semi or equivalent Part No. RH06 or HD06 ECW-U2333KC9 ECW-U2224KCV ECW-U2333KC9 ECH-U1H223JB5 ECH-U1C104JB5 ECH-U1C104JB5 ECS-TICX156R ECJ-2VB1H103K ECH-U1C104JB5 ECH-U1C104JB5 ECJ-1VB1H152K MURS140T3 MURS140T3 MURS120T3 1N4148 BRIDGE-RH06 Diodes Incorporated SMD2825 SMD1210 SMD1210 SMD1210 SMD0805 SMD1210 SMD1210 SMD0603 SMB SMB SMB SOD123 SMD DL-35 SMC SMD2410 PM5022 PM5022 D2-Pak SOT-89 SOT23 SMD0805 SMD0805 SMD1206 SMD0805 SMD0805 SMD0805 SMD0805 SMD0805 SMD0805 SMD0805 SMD0805 SMD0805 SOIC8 0.033 uFd, 250V, 10% SMD1913 0.082 uFd, 100V, 10% SMD1913 15uFd, 16V, Tantalum SMD3528 Diodes Inc. or equivalent ZMM5230B-7 Diodes Inc. or equivalent SMCJ54A-13 Littlefuse R452.500 J.W.
