NXP UM10155 (Discrete Class-D / UcD)

[RobFreak]

Hi everyone,

I have been really fascinated by the discrete Class-D amplifiers and was wondering if anyone has attempted to build the NXP UcD amplifier (UM10155)?

There are many on DIY Audio who have done some version of this ... it's very, very close to the first Hypex modules.

Here is my version
Micro class-d amplifiers UcD / Hysteresis

Today a get much better results from using a real fet driver, a comparator and Opamp ...

Hi (Hej) Baldin, i have been sweeping through your website some weeks ago, the amps look really sweet and the results promising aswell. Have you revised the module since? It could be interesting to build your circuit.
