NCP1001PG

AC DC Converters, Offline Switchers Overview

The NCP1001PG is an integrated off-line switching regulator manufactured by onsemi, designed for flyback converter topologies. It combines a voltage-mode PWM controller with a high-voltage power MOSFET in a single package. The device operates at a nominal switching frequency of 115 kHz and supports a maximum output current of 2A. Key electrical parameters include a minimum input voltage of 7.9V and a nominal input voltage of 8.6V. It is housed in an 8-pin PDIP package with a pitch of 0.300 inches (7.62mm), suitable for through-hole mounting.

AC DC Converters, Offline Switchers Procurement Notes

Verify the specific package variant, as the NCP1001 series includes both DIP and SOIC options. Confirm that the 8-DIP form factor matches your PCB layout requirements. Ensure the thermal management strategy aligns with the device's operating temperature range of -40°C to 125°C TJ. Cross-reference the manufacturer part number with distributor codes to avoid substitution errors.

AC DC Converters, Offline Switchers Selection Notes

Select this component when a compact, integrated solution for low-to-medium power offline applications is required. The fixed 115 kHz frequency aids in EMI filter design. Consider the 2A output current limit and 8.6V nominal input characteristics against system load demands. The PDIP package is preferred for prototyping or applications requiring robust mechanical stability compared to surface-mount alternatives.

AC DC Converters, Offline Switchers Part Context

The NCP1001PG belongs to onsemi's family of integrated off-line switching regulators. These devices are engineered to reduce component count and board space by combining control logic and power switching elements. This integration simplifies the design process for standalone power adapters and auxiliary power supplies commonly found in consumer electronics and industrial equipment.

AC DC Converters, Offline Switchers Replacement Considerations

Check for direct pin-compatible replacements within the same NCP1001 series, such as other packaging variants like NCP1001SO. Verify that any substitute maintains the 115 kHz switching frequency and 2A current capability. Ensure the alternative device supports the same flyback topology and voltage-mode control scheme.
