NCP1201P60G

AC DC Converters, Offline Switchers Overview

The NCP1201P60G is a PWM current-mode controller designed for universal off-line supplies, featuring low standby power and fault protection modes. It operates at a fixed switching frequency of 60 kHz and supports flyback topology. The device utilizes Very High Voltage Integrated Circuit (VHVIC) technology to supply itself directly from the high-voltage rail, eliminating the need for an auxiliary winding. It includes brownout detection, overload protection, overtemperature protection, and short-circuit protection. The component is housed in an 8-DIP package with a maximum supply voltage of 16 V and a breakdown voltage of 500 V.

AC DC Converters, Offline Switchers Feature Summary

• Utilizes VHVIC technology for direct high-voltage rail self-supply without auxiliary windings
• Implements skip cycle mode to maintain high efficiency under light load conditions
• Provides comprehensive fault protection including overload, overtemperature, and short-circuit detection

AC DC Converters, Offline Switchers Applications

• Universal offline AC-DC adapters
• Battery chargers
• Switchmode power supplies requiring low standby power

AC DC Converters, Offline Switchers Procurement Notes

Verify component authenticity through authorized onsemi distributors or certified partners. Confirm the specific suffix 'G' indicates RoHS compliance status as per the latest datasheet revision. Check for obsolescence notices or product change notifications prior to finalizing procurement plans. Ensure storage conditions adhere to moisture sensitivity level specifications to prevent package damage during assembly.

AC DC Converters, Offline Switchers Selection Notes

Select this controller for designs prioritizing minimal standby power consumption and simplified transformer design due to the absence of auxiliary winding requirements. The fixed 60 kHz frequency suits applications where acoustic noise reduction is critical. Consider the 8-DIP package for through-hole mounting requirements. Evaluate the internal brownout detection capabilities against input voltage fluctuation profiles in the target application environment.

AC DC Converters, Offline Switchers Part Context

The NCP1201 series enhances the previous NCP1200 family by reducing optocoupler current requirements and adding Brownout Detection Protection. It shares the core VHVIC architecture but offers improved performance in low-power scenarios. The P60 variant specifically denotes the 60 kHz operating frequency option within the broader NCP1201 lineup, distinguishing it from other frequency variants like the 100 kHz version.
