NCP1607BDR2G

Overview

The NCP1607BDR2G is a power factor correction controller manufactured by onsemi, designed for AC-DC switching power supplies. It operates within a supply voltage range of 9.5V to 20V and supports a switching frequency of 70kHz. The device features a maximum power dissipation of 450mW and is housed in an SOIC-8 surface-mount package with dimensions of 4.90mm x 3.90mm and a height of 1.75mm. It functions across a wide operating temperature range from -40°C to +125°C, with storage capabilities extending from -65°C to +150°C. The component is RoHS compliant and currently holds an active lifecycle status.

Feature Summary

• Integrated power factor correction control for high-efficiency AC-DC conversion
• Supports surface-mount installation in compact SOIC-8 packaging
• Wide thermal operating range suitable for demanding environments

Applications

• AC-DC switching power supply designs
• General-purpose power factor correction circuits
• Consumer electronics power adapters

Procurement Notes

Verify the current lifecycle status and availability directly with authorized distributors or the manufacturer before finalizing procurement plans. Confirm that the specific SOIC-8 package variant matches your PCB footprint requirements. Ensure compliance with RoHS standards if required by your regional regulations. Check for any recent product change notifications that may affect pinout or electrical characteristics. Validate lead times as manufacturing schedules can fluctuate based on demand.

Selection Notes

Select this component when designing power factor correction stages requiring a 70kHz switching frequency and operation within a 9.5V to 20V supply range. Consider its 450mW power dissipation limit for thermal management in enclosed spaces. The SOIC-8 package is suitable for applications prioritizing space efficiency. Ensure the operating temperature range aligns with the environmental conditions of the target application. Compare against alternatives like the NCP1601 series if different switching frequencies or modes are needed.

Part Context

This part belongs to the NCP1607 series of power factor controllers from onsemi. It is categorized under PMIC (Power Management ICs) specifically for PFC applications. The device is distinct from gate drivers like the NCP1393 series or secondary side controllers like the NCP4306. It serves as a primary controller for improving power factor in AC-DC converters, differing from general step-down controllers such as the NCP81xxx series.

Replacement Considerations

The NCP1601BDR2G is listed as a discontinued direct substitute option for similar PFC controller applications. Verify compatibility regarding switching frequency and control mode before substitution.
