About the Product

Ultra-Low Standby Power & Robust Protection for Mining Power Supplies

Boost your crypto mining power supply efficiency with the OB2276CP – a highly integrated, current-mode PWM controller engineered for Whatsminer P222B PSUs and offline flyback converters. This cost-effective IC delivers exceptional energy efficiency with <1W standby power, making it perfect for 24/7 mining operations where reliability and power savings matter most.

 

65KHz Fixed Frequency PWM IC with OCP/OVP/OTP – Ideal for Mining Rig Power Adapters

Key Benefits for Crypto Mining Applications:
✔ Burst Mode Operation – Reduces switching losses under light loads (ideal for variable mining workloads)
✔ Full Protection Suite – Cycle-by-cycle OCP, OVP, OTP, and UVLO prevent PSU failures in harsh conditions
✔ 65KHz Fixed Frequency – Stable switching for clean power delivery to ASIC miners
✔ EMI Reduction Technology – Minimizes interference in high-density mining farms
✔ SOP8 Compact Design – Easy integration into mining PSU repairs and custom power solutions

Trusted by mining hardware technicians and PSU manufacturers, the OB2276CP ensures long-lasting, efficient power conversion for Bitcoin miners, Whatsminer rigs, and industrial mining setups.
