NCS1002DR2G

Overview

The NCS1002DR2G is a secondary-side controller for switch-mode power supplies, manufactured by onsemi. It operates within a supply voltage range of 3V to 32V and draws a typical supply current of 200µA. The device supports constant voltage and constant current regulation modes. It is rated for an operating temperature range from -40°C to +105°C. The component is housed in an 8-SOIC package with a width of 3.90mm (0.154 inches) and utilizes surface-mount installation.

Feature Summary

• Provides integrated constant voltage and constant current control capabilities for secondary-side applications.

Applications

• Secondary-side control in isolated power supply topologies

Procurement Notes

Verify the complete part number including the suffix DR2G to ensure correct packaging configuration. Confirm that the 8-SOIC footprint matches the target PCB layout dimensions. Check the datasheet for specific thermal requirements associated with the 105°C maximum junction temperature rating during operation.

Selection Notes

Select this component when designing isolated converters requiring secondary-side regulation. Ensure the input voltage stays within the 3V to 32V operational window. Verify compatibility with the required switching frequency and feedback loop compensation networks specified in the official documentation.

Part Context

This part belongs to the NCS1002 series of secondary-side controllers. It is functionally related to the NCS1002A variant. Both devices share the same core regulation features but may differ in specific ordering or packaging details as defined by the manufacturer's product line structure.
