TLV62568DBVR Synchronous Buck Converter – Antminer S17e Hashboard Repair IC
The TLV62568DBVR is a 1 A synchronous buck converter from Texas Instruments, packaged in a tiny SOT-23-5 (SC-74A) footprint. It steps down a 2.5–5.5 V input to an adjustable output as low as 0.6 V at up to 1.5 MHz switching frequency — delivering high efficiency with minimal external components. On Antminer S17e hash boards it powers auxiliary logic rails (temperature sensors, clock buffers, communication interfaces) that the ASIC chips rely on for coordinated operation.
Why This Converter Fails on Mining Hash Boards
Hash boards experience constant thermal cycling and voltage transients from the high-current ASIC power domains. Over thousands of hours, these stresses can degrade the TLV62568's internal MOSFETs, causing the output voltage to sag or oscillate. Symptoms include intermittent ASIC communication errors, random chip drop-outs that move positions between reboots, or a hash board that passes cold-start testing but fails under sustained load. Measuring the converter's output with a scope during operation will reveal instability that a static multimeter check misses.
Replacement Procedure
Identify the TLV62568 location — typically marked "14VF" in silk screen — near the hash-board edge connector. Remove the failed part with a fine-tip iron at 300 °C, clean the five pads, and solder the replacement observing pin-1 orientation. Because the SOT-23-5 pitch is wide (0.95 mm), hand soldering is straightforward. After replacement, power the board through a test fixture and verify the output rail reads within ± 3 % of its design target under load before returning the board to production.
