The ON Semiconductor NCP1256ESN65T1G is a low-power offline PWM current mode controller housed in a compact TSOP-6 package. It is designed for cost-effective switch mode power supplies ranging from a few watts up to several tens of watts.
This controller operates at a fixed frequency of 65 kHz or 100 kHz and features frequency foldback down to 26 kHz and skip-cycle operation in light load conditions for improved efficiency. It includes integrated slope compensation and a fixed 4 ms soft-start.
Protection features include timer-based auto-recovery short circuit protection (70 ms), adjustable over power protection (OPP), and adjustable brown-out level. It also supports latched or auto-recovery options for over voltage protection (OVP) and over temperature protection (OTP) events.
The NCP1256ESN65T1G is suitable for AC-DC adapters for portable devices, computers, and tablets. It is supplied in a Surface Mount package (SOT-23-6 Thin, TSOT-23-6) with an operating temperature range of -40°C to 125°C.

The operating voltage range is 8.9V to 28V.
The nominal switching frequency is 65kHz, with a minimum of 26kHz under light load conditions.
It includes over power, over voltage, and short circuit protection with timer-based auto-recovery.
The operating temperature range is -40°C to 125°C.
It is available in a surface-mount SOT-23-6 Thin (TSOT-23-6) package, also known as 6-TSOP.
No, it does not have an internal power switch and requires an external MOSFET.
It provides ±500mA source/sink gate drive capability.
