TPA3136D2PWP

TPA3136D2PWP is a Texas Instruments dual-channel Class-D audio amplifier designed for compact stereo speaker systems. It drives two speakers directly from a single low-voltage supply with high efficiency, minimizing heat and power draw in portable applications. Key features typically include:
- Two bridge-tied outputs (BTL) for stereo speaker drive
- High efficiency and compact footprint
- Integrated protections: undervoltage, overcurrent, over-temperature, short-circuit protection
- Click-free/mute startup and shutdown to avoid pops
- Suitable for filterless (or minimal-filter) speaker connections in many configurations
- Small PWP package ideal for space-constrained devices
Common use cases: portable Bluetooth speakers, small soundbars, docking or USB-C powered audio adapters, and other battery-powered audio products.
Note: exact electrical specs (output power into specific speaker loads, supply range, input types, and pinout) vary by variant; consult the latest datasheet for precise figures and recommended application circuit.

Do you mean a pin‑compatible drop‑in replacement or just similar Class‑D amplifiers (power, supply, package)? Please specify required supply voltage, output power per channel, stereo/mono and package so I can list true equivalents.

Here are the main features of the TPA3136D2PWP (concise):
- Dual-channel Class-D audio amplifier
- Filterless outputs (no external LC filter required)
- High efficiency with reduced heat dissipation
- Pop-free startup with soft-start and mute control
- Built-in protections: overcurrent/short-circuit, overtemperature, undervoltage
- Auto-restart after fault with speaker protection
- EMI reduction via spread-spectrum switching
- Wide supply range and low quiescent current (suitable for portable devices)
- Control interfaces (enable/mute, inputs) and status cues
- Packaging: PWP family (compact package)

TPA3136D2PWP is supplied in a 24‑pin (4 × 4 mm) WQFN (PWP) package. Function: it is a Class‑D stereo audio power amplifier. Typical pin roles are:
- Power: PVDD (power supply pins), AVDD (analog supply if present), and exposed pad for PGND/thermal.
- Grounds: PGND/AGND and exposed pad.
- Inputs: differential/unbalanced audio inputs (LIN+, LIN–, RIN+, RIN–).
- Outputs: bridged outputs for each channel (LOUT+, LOUT–, ROUT+, ROUT–).
- Control/diagnostics: MUTE/EN or ENABLE, MODE/SYNC/CLK, FAULT/THERM/OC (diagnostic) pins.
- Misc: bias/boot/decoupling pins (VREF, BST, filter caps).
