Description

Shop Ncp1251 Current-mode Pwm Controller Ic Sot236 and more Circuitos Integrados at Latinafy.com

The ON Semiconductor NCP1251 is a highly efficient PWM controller designed for robust offline power supplies. It operates in a compact TSOP-6 package, providing reliable performance with a supply range of up to 28V. With its fixed frequency operation of either 65 kHz or 100 kHz, it ensures consistent delivery of power even under varying load conditions. The controller features integrated Over Power Protection (OPP), enabling customized power management without sacrificing standby efficiency. It’s an ideal component for applications requiring high-quality power supplies, such as AC-DC converters for TVs and printers.

The NCP1251 from ON Semiconductor is a cutting-edge PWM controller that excels in delivering high performance for offline power supplies while maintaining a compact design. With a supply voltage range of up to 28V, this highly integrated solution operates at either 65 kHz or 100 kHz, allowing for precise power management. Notably, when the secondary-side power decreases, the controller effectively folds back its switching frequency to a minimum of 26 kHz, and further enters skip cycle mode to limit peak current. This makes it particularly effective in light load conditions, ensuring both efficiency and reliability. Additionally, the NCP1251 incorporates a proprietary integrated Over Power Protection (OPP) mechanism, allowing users to optimize power delivery without compromising standby performance. It features a latched Over Voltage Protection (OVP) that safeguards against potential device failures, offering resilience against open loop operation problems. The internal soft-start function takes 4 milliseconds, effectively smoothing the start-up process, while an innovative timer-based short circuit protection system enhances overall safety by allowing precise selection of protection trip points. The device is Pb-free, making it a compliant and environmentally friendly choice for various applications, such as AC-DC converters for TVs, set-top boxes, and offline adapters for notebooks.

Usage ideas Utilize the NCP1251 in designing reliable AC-DC converters for televisions and printers. Implement it in offline adapters for notebooks and netbooks, ensuring efficient power management. The controller can also be integrated into various consumer electronics that require a robust power supply. Consider using it in applications where low standby power consumption is critical. Enhance your product designs with this versatile component for better energy efficiency and protection features.
