NCP1653PG

Overview

The NCP1653PG is a 1.5 A average current mode power factor controller manufactured by onsemi, designed for high-performance PFC applications. It operates within an input voltage range of 9.95 V to 18 V and supports switching frequencies up to 110 kHz. The device functions reliably across a temperature range of -40°C to +125°C and is housed in a lead-free, RoHS-compliant SOP-8 plastic package with a 1.27 mm pin pitch.

Feature Summary

• Implements average current mode control for precise power factor correction
• Integrated 1.5 A driver capability for efficient gate drive performance
• Designed for wide operating temperature ranges suitable for automotive environments

Applications

• Power factor correction stages in AC-DC converters
• Automotive electronics power supplies
• Industrial power management systems

Procurement Notes

Verify the specific suffix 'PG' against official datasheets to confirm package and material specifications. Ensure compliance with RoHS directives and check for any obsolete status or lifecycle changes before finalizing procurement plans.

Selection Notes

Select this component when average current mode control is required for improved line regulation and transient response. Consider the 1.27 mm SOP-8 package for space-constrained designs requiring robust thermal performance in automotive or industrial settings.

Part Context

This part belongs to the NCP165x family of power factor controllers from onsemi. It shares functional similarities with variants like NCP1653ADR2G but differs in packaging and ordering suffixes. The family targets high-efficiency PFC solutions for various power supply architectures.

Replacement Considerations

Check for direct substitutes such as NCP1653ADR2G, ensuring pin compatibility and electrical parameter alignment. Verify that alternative packages meet mechanical constraints without compromising thermal or electrical performance.
