ML4876ER-NL4C0092

Display Drivers Overview

The ML4876ER is a high-performance, single-chip power factor controller designed for critical conduction mode (CrM) flyback converters. It integrates a voltage-mode PWM controller with an active PFC front-end stage. The device features a built-in high-voltage startup circuit and operates from a wide supply voltage range. Key electrical parameters include a switching frequency up to 100 kHz, a peak current limit threshold typically set by external components, and operation within a temperature range of -40°C to +85°C. The controller utilizes cycle-by-cycle current limiting and offers soft-start capabilities to reduce inrush current during initialization.

Display Drivers Procurement Notes

Verify the specific suffix 'NL4C0092' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications and lot traceability requirements. Ensure that the ordering part number matches the exact revision level required for your design to avoid compatibility issues with existing PCB layouts or firmware configurations.

Display Drivers Selection Notes

Select this component when designing flyback converters requiring high power factor correction without complex digital control. It is suitable for applications demanding moderate power levels where simplicity and cost-effectiveness are prioritized. Consider the thermal performance of the SOIC-16 package and ensure adequate heatsinking if operating near maximum load conditions.

Display Drivers Part Context

Fairchild Semiconductor, now part of ON Semiconductor, produced the ML4876 series as part of their analog control portfolio. This chip belongs to a family of PFC controllers aimed at replacing discrete solutions with integrated monolithic designs. The ML4876 specifically targets the transition from discontinuous conduction mode to critical conduction mode for better efficiency profiles across varying load conditions.

Display Drivers Replacement Considerations

Check for direct pin-compatible alternatives such as the ML4876ER-NL4C0093 or other CrM PFC controllers from ON Semiconductor. Verify that any substitute maintains the same voltage ratings and control loop characteristics to ensure seamless integration into existing designs.
