UCC3808APWTR-2G4

DC DC Switching Controllers Overview

The UCC3808APWTR-2G4 is a low-power current-mode push-pull PWM controller manufactured by Texas Instruments. It operates within an input voltage range of 9 V to 13 V, with a nominal rating of 10 V. The device supports boost and buck topologies and features a switching frequency up to 1 MHz. It provides two outputs with a maximum duty cycle of 50% (specifically 49% in some documentation) and delivers a gate drive output current of 1 A. The component has a fall time of 25 ns and functions reliably between 0°C and +70°C. It is housed in an 8-pin TSSOP package.

DC DC Switching Controllers Feature Summary

• Implements current-mode control for stable regulation in switch-mode power supplies.
• Utilizes push-pull pulse width modulation architecture for efficient power conversion.
• Integrates high-current gate drivers capable of sourcing 1 A for direct transistor control.

DC DC Switching Controllers Applications

• Low-power DC-DC converter designs
• Battery-powered equipment requiring efficient power management
• Industrial control systems utilizing push-pull topologies

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS adherence as per Texas Instruments standards. Confirm the 'PW' package designation corresponds to the TSSOP-8 form factor required for your PCB layout. Ensure the '-2' variant matches the intended pinout or functional configuration compared to other family members. Cross-reference the datasheet revision date to ensure compatibility with your design specifications.

DC DC Switching Controllers Selection Notes

Select this component when designing low-power applications requiring current-mode control and push-pull topology. It is suitable for systems needing a 1 A gate drive capability and operation within the 9 V to 13 V input range. Consider the TSSOP-8 package constraints and the 0°C to +70°C operating temperature range during thermal management planning. Evaluate the 1 MHz switching frequency against EMI requirements.

DC DC Switching Controllers Part Context

This part belongs to the UCC3808 family of low-power current-mode controllers from Texas Instruments. The family includes variants such as UCC3808AN-1G4 and UCC3808ADTR-2G4, which differ primarily in packaging (PDIP, SOIC) and suffix designations. These controllers are designed for cost-effective, high-efficiency power supply solutions in consumer and industrial electronics.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include UCC3808AN-1G4 and UCC3808ADTR-2G4. Verify package compatibility (TSSOP vs. PDIP/SOIC) and confirm that the specific suffix variations do not alter internal functionality or pin assignments before substitution.
