Hello!
I design audio amplifier on TAS5630DKD.
My problem: When output power approximately 100W - amplifier switchable in protect mode (supposedly in Overload protection).
Used one output.
Herewith:
1. Power voltage (PVDD) 50V;
2. Load 4Ohm (Resistive);
3. Coil - IHLP-5050CE-01 - 6.8uH
4. Mode - BTL;
5. Input - Sine 1kHz (variable voltage);
3. Output power to 100W (Power Current ~2.5A)-amplifier switchable in protect mode.
That already did:
1. Power 30-50V; - no change
2. Serial connect coil --> 13.6uH; - no change
3. change TAS5630; - no change
4. Roc_adj 24k -->33k; - no change
5. No load; - good
When increase the input amplitude current feeding increases and getting to 2,5А - amplifier is disconnected (Overload protect). Launch possible only if RESET --> low, and --> high.
Overload protect - ON:
SD - 0;
OTW - 1.
