NCP1623ASNT1G

Overview

The NCP1623ASNT1G is a Power Factor Correction (PFC) controller manufactured by onsemi, designed for critical conduction mode (CRM) and discontinuous conduction mode (DCM) applications. It operates within an input voltage range of 2.5 V to 36 V and supports a maximum drive capability of 800 mA. The device features a variable switching frequency with a typical operation at 30 kHz and includes an under-voltage lockout threshold of 10.5 V. Packaged in a TSOP-6 configuration, it functions as a step-up topology controller suitable for compact power supply designs.

Feature Summary

Integrates follower boost functionality to optimize efficiency across varying load conditions
Features valley sync frequency foldback for enhanced performance in DCM operation
Includes dynamic response enhancement for rapid line and load transient compensation

Applications

Compact PFC stages for AC-DC power supplies
Systems requiring high power factor and efficiency optimization
Downstream converters utilizing follower boost topologies

Procurement Notes

Verify component authenticity through authorized distribution channels due to potential counterfeit risks. Confirm RoHS compliance status via official documentation before integration. Ensure the specific suffix matches design requirements as ordering variations may exist. Validate package integrity upon receipt to prevent soldering defects during assembly processes.

Selection Notes

Select this controller for applications demanding high efficiency in small form factors. The integrated follower boost suits designs where downstream converters tolerate input voltage variations. Consider the low VCC start threshold for systems powered by auxiliary rails. Evaluate thermal management needs given the TSOP-6 package constraints in dense layouts.
