Overview
The NCL38046AADR2G is a secondary side controller from onsemi designed for switch-mode power supplies. It operates as a CC/CV amplifier to ensure precise constant current regulation and includes a CP (Constant Power) function. The device supports a 12 V operating supply voltage and delivers a fixed 3.3 V output. It functions within an ambient temperature range of -40°C to +125°C and utilizes SMD/SMT installation styles in SOIC-8 packaging.
Feature Summary
- Provides precise constant current regulation via integrated CC/CV amplification
- Incorporates constant power limiting functionality for enhanced protection
- Operates as a secondary side controller for isolated power topologies
Applications
- LED driver power supplies requiring precise current control
- Battery charging systems utilizing constant current/constant voltage profiles
- General purpose isolated DC-DC converters with secondary side feedback
Procurement Notes
Verify the specific suffix AADR2G against the manufacturer datasheet to confirm package type, tape and reel specifications, and RoHS compliance status. Ensure the ordering code matches the exact pinout and thermal characteristics required for your PCB layout. Cross-reference the component marking with official onsemi identification guides to prevent counterfeit substitution during assembly.
Selection Notes
Select this component when secondary side regulation is preferred over primary side control for improved accuracy. It is suitable for designs requiring integrated constant power limiting without external circuitry. Consider the SOIC-8 package constraints and the 12 V supply requirement when designing the bias network. Evaluate thermal performance at the maximum operating temperature of +125°C.
Part Context
This part belongs to the NCL38046 series of secondary side controllers. It complements onsemi's portfolio of LED lighting drivers and power management ICs. The series focuses on providing robust regulation features for applications demanding high precision and reliability in isolated power conversion architectures.
Replacement Considerations
Consult the official onsemi replacement guide or datasheet revision history for direct pin-to-pin alternatives. Verify functional equivalence regarding the CC/CV amplifier architecture and CP function implementation before substituting.
