TEA2095T Synchronous Rectifier Controller Chip for Antminer APW11 PSU Repair

TEA2095T Synchronous Rectifier Controller | Adaptive Gate Drive IC for Antminer APW11 PSU Repair

The TEA2095T is a synchronous rectifier controller chip for switching power supplies. Uses adaptive gate drive and independent dual driver stages to optimise efficiency across the full load range — exactly the characteristics needed on the Antminer APW11 power supply's secondary-side rectification stage. When this chip fails, the APW11 typically reports no output or unstable output under load.

Headline specs: dual synchronous rectification, 4.5V to 38V supply range, 1MHz switching, 90µA supply current in energy-save mode, -25mV regulation level. The adaptive gate drive method matches drive timing to the actual MOSFET characteristics, keeping efficiency high whether the PSU is at light or heavy load.

When to Replace the TEA2095T

• PSU no output — synchronous rectifier stage dead, secondary side not regulating.
• Output sagging under hashing load — degraded driver behaviour, MOSFETs not switching cleanly.
• Excessive heat on secondary-side MOSFETs — gate timing off, MOSFETs running in linear region briefly each cycle.
• Audible squealing or instability not present in normal operation — controller drift.
• Visible damage on the IC package after a fault event.

FAQ — TEA2095T Synchronous Rectifier Controller

Q: How do I confirm the TEA2095T is the failed part?
A: Scope the gate-drive outputs to the secondary-side MOSFETs with the PSU trying to start. Healthy controller produces clean PWM pulses on both SR channels in proper interlock timing. No output, stuck high/low, or distorted timing = chip failed.

Q: Always replace the MOSFETs at the same time?
A: Recommended. The SR MOSFETs are usually stressed when the controller fails — replacing both together avoids a second repair cycle a few weeks later. Inspect the secondary MOSFETs for discolouration as a quick check.

Q: Rework profile?
A: Standard SMD rework. Preheat to 100°C, hot air at 320°C with flux paste. Watch for warpage on the small body. Verify all pins solder cleanly under magnification before powering up.
