UCC1802J883B

DC DC Switching Controllers Overview

The UCC1802J883B is a low-power BiCMOS current-mode PWM controller designed for high-efficiency power conversion applications. It operates within a supply voltage range of -0.1V to 11V and supports switching frequencies up to 1000kHz. The device is housed in an 8-pin CDIP (JG) package, suitable for rugged environments with an operating temperature range of -55°C to 125°C.

DC DC Switching Controllers Feature Summary

• Implements current-mode pulse-width modulation control architecture
• Utilizes low-power BiCMOS technology for efficient operation
• Engineered for resonant and standard PWM converter topologies

DC DC Switching Controllers Applications

• High-frequency DC-DC converters
• Resonant power supply designs
• Military and aerospace electronic systems requiring radiation-hardened or high-reliability components

DC DC Switching Controllers Procurement Notes

Verify the specific suffix J883B indicates military-grade qualification or specific lot traceability requirements. Confirm the package type matches the required 8-pin CDIP form factor. Ensure the supplier provides documentation verifying the component's compliance with the specified -55°C to 125°C operating temperature range and original Texas Instruments manufacturing standards.

DC DC Switching Controllers Selection Notes

Select this component when designing systems that require precise current-mode control with low quiescent power consumption. It is appropriate for applications demanding wide input voltage tolerance and high-frequency switching capabilities. Consider the ceramic DIP package for environments requiring robust mechanical stability and thermal performance under extreme temperature conditions.

DC DC Switching Controllers Part Context

This part belongs to the UCC1802 series of low-power BiCMOS current-mode PWM controllers from Texas Instruments. The J883B suffix typically denotes a specific military or high-reliability variant of the standard UCC1802 controller, distinguished by its packaging and environmental testing specifications compared to commercial grade equivalents.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include other parts within the UCC1802 family, such as the UCC1802J, provided they meet the same package and environmental constraints. Verify compatibility with existing PCB footprints and control loop compensation networks before substitution.
