QUICK START GUIDE Demonstration System EPC9106

DESCRIPTION

The EPC9106 demonstration board is a reference design for a 150 W /

8 Ω Class D audio amplier. The demonstration board uses a

Bridge-Tied-Load (BTL) design, composed of four ground-referenced

Half-Bridge Output Stages. This architecture and topology allows

scalability and expandability.

The EPC9106 reference design has demonstrated 96% eciency at

150 W / 8 Ω, and 92% eciency at 250 W / 4 Ω.

The EPC9106 demonstration board features the EPC2016C

enhancement mode (eGaN®) eld eect transistor (FET), as well as

the Texas Instruments LM5113 gate driver.

A complete block diagram of the circuit is given in figure 1. For more

information on the EPC2016C eGaN FET please refer to the datasheet

available from EPC at www.epc-co.com. The datasheet should be read

in conjunction with this quick start guide.

QUICK START PROCEDURE

The EPC9106 demonstration system is easy to set up to evaluate the

performance of the EPC2016C eGaN FET in a Class D audio amplifier

application. Refer to figure 2 for proper connection and measurement

setup before following the testing procedures.

The EPC9106 can be operated using one of two alternative methods:

a. High Performance Setup

b. Lower Performance Setup

a. High Performance Setup

1. Connect the left/right analog inputs to the balanced analog input

XLR connectors

2. Connect the left/right analog input cables to the audio source

(pre-amp)

a. Use a CD/DVD player with a high-performance pre-amp

3. Turn the master volume control fully counter-clockwise

(minimum volume)

4. Connect the high-voltage power supply

5. Bring up both “+”and “–” power supply rails simultaneously

(use a tracking power supply). Both channel LEDs will remain RED

until ±20 V is reached.

6. Adjust high voltage power supply rails to around ±27 VDC

7. Connect left and right outputs to the loudspeaker of choice

NOTE: While both loudspeaker outputs are ground-referenced, neither is connected

to ground. DO NOT CONNECT EITHER OF THESE LOUDSPEAKER OUTPUTS TO ANY

SYSTEM OR TEST EQUIPMENT GROUND!!

8. Play audio source

9. Adjust master volume control to appropriate listening level

Input Processing & Drivers

b. Lower Performance Setup

1. Connect the left/right analog inputs to the unbalanced analog

input RCA phono connectors

2. Connect the left/right analog input cables to the audio source

a. Use a CD/DVD player with analog audio outputs

b If you use an MP3 player (or iPod), only use wave les,

or PCM audio – DO NOT USE MP3 les for demo!)

3. Turn the master volume control fully counter-clockwise

(minimum volume)

4. Connect the high-voltage power supply

5. Bring up both “+”and “–” power supply rails simultaneously

(use a tracking power supply). Both channel LEDs will remain RED

until ±20 V is reached.

6. Adjust high voltage power supply rails to around ±27 VDC

(use a tracking power supply)

7. Connect left and right outputs to the loudspeaker of choice

NOTE: While both Loudspeaker Outputs are Ground-Referenced, Neither is con-

nected to Ground. DO NOT CONNECT EITHER OF THESE LOUDSPEAKER OUTPUTS TO

ANY SYSTEM OR TEST EQUIPMENT GROUND!!

THERMAL CONSIDERATIONS

With this high eciency, the EPC9106 design allows for the complete

removal of any classical or historical heat sink requirement. This

elimination of the heat sink also reduces the potential contribution to

radiated EMI/EMC emissions. However, care must be taken to not exceed

the absolute maximum die temperature of 150°C and stay within the

constraints of the other components within the circuit.

NOTE. The EPC9106 demonstration board does not have any thermal protection on board.

Power block, no heatsink, eGaN FETs.
