1. Quick Start with P-N-P Kit Included below is a quick checklist of setup steps to get the TPA1517DWP up and running fast. 1. Set S1 to the “off” position. 2. Align the TPA1517DWP with socket U2, such that the side with 4 pins is adjacent to socket U1, and firmly connect it to the P-n-P board. 3. Check the power supply jumper setting on the P-n-P board.
Introduction 1.1 Introduction The TPA1517DWP EVM (SLOP106) is designed to provide the circuitry required to evaluate the TPA1517DWP performance without having to invest in a PCB layout or assembly. Refer to the application note in the TPA1517 data sheet (SLOS162A) for a description of the circuit configuration and selection of components. 1.2 Layout Description Figure 1 - TPA1517DWP Lit.

Operation Notes The connection pins of the TPA1517DWP EVM are on a 0.1” grid for easy interface to standard plugboard based prototype systems. The thermal layout of the EVM is important. Linear Audio Power Amplifiers dissipated large amounts of heat during operation. The data sheet for the TPA1517 (SLOS162A) details heat dissipation for 12 and 14.5 volt operations. The PowerPADTM package has an exposed thermal pad on the underside of the IC.

Controls 2.3 Controls Mute/Standby Select - S1: Jumper in place sets low current standby mode. Jumper out sets mute mode. Mode is activated by Switch S3 or external TTL input at Mute input. Depop Select - S2: Jumper in place selects enhanced Depop mode. Jumper out disables depop circuitry. Mute Input/Switch - S3: Low activates mute/standby (S1) circuitry. Switch S3 is a momentary action push button. Press S1 to mute. R1/R2 Gain Control Pots: 3/4 turn adjusts amplifier Volume. Clockwise increases volume.
