About the Product
OB2268CP PWM Control IC - Enhanced Performance for Whatsminer P222B Power Supply
The OB2268CP PWM Control IC is the ultimate solution for high-performance and cost-effective offline flyback converter applications, specifically designed for power classes above 20W. This highly integrated current mode PWM control IC is engineered to deliver outstanding performance, low standby power consumption, and maximum reliability, making it the perfect choice for any design, including the Whatsminer P222B power supply.
High-Performance PWM Control IC for Offline Flyback Converter Applications
With its low start-up and operating current, the OB2268CP ensures reliable start-up design and allows for the use of large-value resistors, effectively minimizing standby power consumption. The internal slope compensation enhances system large-signal stability, effectively reducing sub-harmonic oscillations and delivering superior performance and efficiency.
Optimize Power Efficiency and Reliability with OB2268CP PWM Control IC
The OB2268CP PWM Control IC offers a complete protection range and automatic self-recovery functions, including cycle-by-cycle current limit (OCP), overload protection (OLP), over-temperature protection (OTP), VDD over-voltage protection (OVP), and under-voltage lockout (UVLO). The gate drive output is clamped to a maximum of 18V to provide robust protection for the power MOSFETs.
Applications:
- Laptop power adapter
- PC/TV/STB power supply
- Open switching power supply
- Battery charger
- Specifically designed for the Whatsminer P222B power supply
