NCV3843BVDR2

Overview

The NCV3843BVDR2G is an analog SMPS PWM controller manufactured by onsemi, designed for boost and flyback topologies. It operates with a switching frequency of 500 kHz and supports a maximum duty cycle of 96%. The device provides one output channel with a rated output current of 1 A and an output voltage of 1 V. It functions within a temperature range of -40°C to +125°C and utilizes an SOIC-8 surface-mount package. The component meets AEC-Q100 automotive qualification standards.

Feature Summary

Supports boost and flyback converter topologies
Automotive qualified under AEC-Q100 standards
Operates across extended industrial temperature ranges

Applications

Automotive power supply systems
Industrial DC-DC conversion circuits
Battery charging controllers

Procurement Notes

Verify the complete part number includes the suffix 'G' for lead-free compliance and RoHS adherence. Confirm the 'D1R2' or 'DR2' designation matches the required tape-and-reel packaging quantity. Ensure the automotive grade (NCV prefix) aligns with specific reliability requirements for your target application environment.

Selection Notes

Select this component when designing isolated or non-isolated converters requiring high efficiency at 500 kHz. The SOIC-8 package suits space-constrained layouts. Verify input voltage ranges against the specific topology requirements, as datasheet specifications may vary between similar family members like the standard NC variant.

Part Context

This part belongs to the NCV3843B series of switching controllers from onsemi. It shares functional similarities with other current-mode PWM controllers but is distinguished by its automotive qualification and specific thermal ratings. The series targets robust power management solutions in demanding environments.

Replacement Considerations

Check for direct substitutes such as NCV3843BVD1R2G which shares identical electrical characteristics and pinout. Verify package compatibility and thermal performance before swapping components in existing designs.
