Overview
The NCP1370ADR2G is a dimmable quasi-resonant primary side current-mode controller designed for LED TV backlight applications. It targets isolated flyback and non-isolated constant current topologies, operating at a fixed frequency of 65 kHz with an input voltage range of 9.5 V to 26 V. The device supports a maximum output current of 800 mA and features adjustable output voltage regulation. Packaged in an SOIC-8 surface-mount format, it operates within a temperature range of -40 °C to +125 °C.
Feature Summary
- Primary side sensing capability eliminates the need for secondary feedback circuitry, biasing windings, and opto-couplers.
- Quasi-resonant peak current-mode control operation optimizes efficiency by switching at voltage valleys.
- Supports analog and digital dimming modes, which can be combined to enhance dimming precision.
- Integrated robust safety protections including programmable peak current limit and overvoltage protection.
Applications
- LED TV backlight drivers
- Isolated flyback converter designs
- Non-isolated constant current LED topologies
Procurement Notes
Verify the specific suffix 'A' indicates the assembly location variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the specified SOIC-8 package dimensions and thermal requirements for the target application environment.
Selection Notes
Select this component for designs requiring high efficiency without secondary side feedback complexity. The primary side regulation feature simplifies bill of materials by removing opto-couplers. Suitable for applications needing precise constant current control with integrated dimming capabilities and wide input voltage tolerance.
Part Context
This part belongs to the NCP1370 series of LED lighting driver ICs from onsemi. The series focuses on simplified design solutions for backlighting by leveraging primary side regulation technology. It represents a specialized solution for consumer electronics display power management.
Replacement Considerations
The NCP1370BDR2G is a confirmed substitute within the same family, differing primarily in the device option suffix which may affect specific protection behaviors or assembly details.
