NCP10672BD060R2G

AC DC Converters, Offline Switchers Overview

The NCP10672BD060R2G is a high-voltage switcher from the NCP1067X series, integrating a fixed-frequency current-mode controller with a 700 V MOSFET in an SOIC-7 package. It operates at a switching frequency of 60 kHz with a maximum duty cycle of 72%. The device features a low on-resistance of 12 Ω for the internal MOSFET and supports output currents up to 8 mA. It functions within a temperature range of -40 °C to +125 °C, drawing 840 µA of supply current at 9 V. Designed for both isolated (flyback) and non-isolated (buck) topologies, it includes dynamic self-supply capabilities.

AC DC Converters, Offline Switchers Procurement Notes

Verify the specific suffix BD060R2G against the manufacturer's latest datasheet to confirm pinout compatibility and thermal characteristics. Ensure the SOIC-7 package dimensions match your PCB footprint requirements. Cross-reference the RoHS compliance status with current environmental regulations before finalizing procurement orders.

AC DC Converters, Offline Switchers Selection Notes

Select this component when a 700 V breakdown voltage is required alongside integrated control logic. The 12 Ω Rds(on) makes it suitable for higher current demands compared to other variants in the series. Consider the 60 kHz operating frequency for EMI filtering constraints and verify that the SOIC-7 package fits within the available board space constraints.

AC DC Converters, Offline Switchers Part Context

This part belongs to the NCP1067X family of high-voltage switchers designed for low-power switched-mode power supplies. The series offers different MOSFET on-resistances and current setpoints to accommodate various power levels. The NCP10672 variant specifically targets applications needing lower conduction losses due to its reduced internal resistance.

AC DC Converters, Offline Switchers Replacement Considerations

Direct substitutes include other NCP1067X variants such as NCP10670 or NCP10671, provided the difference in Rds(on) and current limits aligns with the application requirements. Verify package compatibility and electrical parameter overlaps before substitution.
