UP1529Q UP9305W UP1542S UP1529QSU8 SOP-8 Power chip Antminer Hashboard

UP1529Q UP9305W UP1542S SOP-8 Power Chip | Antminer L3+ S9 Hashboard IC

The UP1529Q, UP9305W, UP1542S, and UP1529QSU8 are SOP-8 package power management ICs used on Antminer L3+, L3++, and S9 series hashboards. These chips regulate voltage for the ASIC processors on each hashboard — when one fails, the affected voltage domain stops hashing, causing partial or complete hashboard failure. This listing covers multiple compatible part numbers (UP1529Q, UP9305W, UP1542S, UP1529QSU8) that serve the same function across different hashboard production runs.

UP1529Q Power IC: Voltage Regulation on L3+ and S9 Hashboards

Each Antminer L3+ and S9 hashboard contains multiple voltage regulation stages that power groups of ASIC chips. The UP1529Q-series ICs are step-down (buck) converter controllers in a compact SOP-8 package. When these chips fail, symptoms include: specific chip domains reporting zero hash, abnormal voltage readings on the affected hashboard section, or the hashboard initializing but not producing expected hash rate. The SOP-8 package makes these chips straightforward to replace with basic hot-air rework equipment.

Antminer L3+ & S9 Hashboard Power IC Repair

When diagnosing partial hash rate loss on an L3+ or S9 hashboard, check the voltage domains around the affected chip groups. A failed UP1529Q will typically show incorrect output voltage (too high, too low, or absent) on the associated power rail. Use a multimeter to verify, desolder the suspect IC, and replace. For complete hashboard diagnostics, a K8pro ASIC Miner Tester or the K3L Antminer Tester provides chip-level scanning. Pair with the BM1387/BM1397 Universal Tin Tool when also replacing ASIC chips on the same board. The APW7 1800W PSU powers both L3+ and S9 miners.
