Hi Sir,
We have LED Driver request.
Could you help provide solution can meet as below spec ? Thanks,
1. Input voltage 25.4Vdc, output voltage 27-48Vdc can be adjustable (control signal is from 0 to 3.0V respectively). If IC can’t adjust its output voltage directly, we may add additional circuit by ourselves.
2. Output current: 0-4.7A.
3. Suggestion Vcc=12V.
4. Current mode control, main MOSFET current can be limited cycle by cycle.
5. Expecting Operating frequency: 100kHz-200kHz.
6. Soft start function.
7. Better to have output OVP and input UVP detection function. Output OVP need to latch while input UVP is auto-recovery type.
8. Good dynamic response to pulse load (refer to LED current at 3D TV mode).
9. Package: SMD type, SOIC or others.
