The ON Semiconductor NCP1256ASN65T1G is a low power offline PWM current mode controller designed for cost-effective switch mode power supplies. It operates at a fixed frequency of 65 kHz and can be supplied up to 28V.
This controller features frequency foldback down to 26 kHz and skip-cycle operation in light load conditions. It includes protection features such as timer-based auto-recovery short circuit protection, adjustable over power protection (OPP), and an adjustable brown-out (BO) pin. The device also has latched inputs for OVP and OTP events, offering improved robustness.
Housed in a compact 6-TSOP package, the NCP1256ASN65T1G is suitable for surface mounting. Its operating temperature range is -40°C to 125°C (TJ), making it versatile for various applications.
Typical applications include AC-DC adapters for portable devices, computers, and tablets. The device supports a duty cycle of 80% and has a drive capability of ±500 mA.
