ML4832CP

Overview

The ML4832CP is a power factor and fluorescent light controller manufactured by Fairchild Semiconductor. It utilizes current-mode control architecture within a BICMOS process. The device is housed in an 18-pin plastic DIP package (PDIP-18). It integrates functions for power factor correction and ballast control, operating as an electronic dimming ballast controller.

Feature Summary

• Integrates power factor correction and fluorescent light control functions
• Employs current-mode control architecture for performance optimization
• Designed specifically for electronic dimming ballast applications

Applications

• Electronic dimming ballast systems
• Fluorescent lighting power factor correction circuits
• Integrated ballast controller designs

Procurement Notes

Verify the manufacturer origin carefully, as this component has been produced by multiple entities including Micro Linear, Qorvo, and Rochester Electronics under the same part number. Confirm that the specific unit acquired matches the Fairchild Semiconductor specification requirements for your design implementation.

Selection Notes

Select this component when a combined PFC and light controller solution is required in a through-hole package. Ensure the application supports the current-mode control topology and fits the thermal and electrical constraints of the 18-pin DIP form factor.

Part Context

This part belongs to the ML4832 family of controllers. Variants such as the ML4832CS exist in surface-mount packages. The CP suffix denotes the dual in-line package configuration suitable for legacy or high-reliability mounting styles.

Replacement Considerations

ML4832CS serves as a pin-compatible alternative in SOIC-18 packaging.
