The NCP1203P40G from ON Semiconductor is a PWM Current-Mode Controller designed for universal off-line power supplies. It is housed in an 8-PDIP package and supports a wide operating voltage range of 7.8V to 16V.
This controller features a fixed operating frequency of 40 kHz, with options for 60 kHz and 100 kHz available in other variants. It includes essential protection features such as Over Load, Over Temperature, and Short Circuit protection, along with an auto-recovery function. The device also incorporates an internal high-voltage startup current source and supports an 80% duty cycle.
Designed for efficiency, the NCP1203P40G offers features like adjustable skip-cycle capability for improved light-load efficiency and extremely low no-load standby power. Its current-mode control provides inherent pulse-by-pulse current limiting and good audio susceptibility. The component is suitable for applications like AC-DC adapters, battery chargers, and auxiliary power supplies.
Mounting is via through-hole method. The operating temperature range is from -40°C to 125°C (TJ). The device is RoHS3 compliant and Halogen Free.
