uP9650AQR1 60A Powering Chip for Iceriver KS0 Pro Hashboard
Enhance the performance of your Iceriver KS0 Pro hashboard with the high-performance uP9650AQR1 powering chip. Designed to replace the existing powering chip, this integrated solution offers optimized drivers and MOSFETs for high-current, high-frequency, synchronous step-down DC-DC converters. Drop-in replacement when the original powering chip fails on KS0 Pro.
Housed in a compact VQFN6×5-39L package, equipped with advanced features for precise module temperature reporting and on-chip synchronous MOSFET current monitoring. Comprehensive protection mechanisms — cycle-by-cycle overcurrent protection, phase fault detection, preliminary overvoltage protection, VCC/VDRV UVLO protection, and thermal shutdown — ensure reliable and safe operation across continuous mining loads.
Typical Use in Iceriver KS0 Pro Repair
- KS0 Pro hashboard powering chip failure — drop-in replacement for failed uP9650AQR1.
- Domain power restoration — restoring failed buck-converter stage powering ASIC array.
- Hot-failure recovery — replacement after thermal events damage the powering chip.
- Production refurbishment — bulk powering chip inventory for KS0 Pro rework lines.
- General high-current synchronous buck — laptop, desktop, GPU VRM applications outside mining.

FAQ — uP9650AQR1 Powering Chip
Q: How do I diagnose a failed uP9650AQR1 on KS0 Pro hashboard?
A: Typical signs: domain Vout absent, hashboard reports missing domain, ASIC chips fed by that domain offline. Test by measuring Vout at the powering chip output. Visible damage to VQFN6×5 package confirms catastrophic failure.
Q: Will it work on KS0 (non-Pro) hashboards?
A: Verify by silk marking on the KS0 board. Different sub-models may use different powering chip variants — the uP9650AQR1 is validated for KS0 Pro specifically. Check existing chip marking before ordering for non-Pro KS0.
Q: What's the difference between uP9650AQR1 and similar UPI parts?
A: The UPI uP965x family has multiple variants with different current ratings, package options, and feature sets. AQR1 is the variant matched to KS0 Pro. For OEM-spec repair, stick with AQR1 specifically.
Q: Bulk pricing for Iceriver repair shops?
A: Yes — email contact@lys-sz.com with your monthly KS0 Pro board rework volume for tier pricing.
