TPS40090PWR

DC DC Switching Controllers Overview

The TPS40090PWR is a four-channel multiphase buck DC/DC controller manufactured by Texas Instruments. It operates within a switching frequency range of 100 kHz to 1 MHz and supports output voltages from 700 mV to 3.3 V. The device is designed for high-current applications, supporting up to 120 A output current. It functions within an operating temperature range of -40°C to +85°C and utilizes a TSSOP-24 package. The controller features clock synchronization capabilities and includes control characteristics such as current limiting, enable, frequency control, power good, and soft start.

DC DC Switching Controllers Feature Summary

• Supports four-phase synchronous buck topology for high-current distribution
• Enables precise load regulation through integrated voltage mode control
• Provides flexible switching frequency adjustment via external resistor or clock sync

DC DC Switching Controllers Applications

• High-performance computing systems requiring multi-phase power delivery
• Graphics processing unit (GPU) core voltage regulation
• Central processing unit (CPU) power management modules

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'PWR' indicates the tape and reel packaging variant distinct from tube-packaged versions like 'PW'. Confirm RoHS compliance status through the official datasheet before integration. Ensure the design accommodates the thermal requirements associated with the TSSOP-24 package during operation.

DC DC Switching Controllers Selection Notes

Select this component when designing systems requiring four independent phases for current sharing and ripple cancellation. Consider the maximum duty cycle and input voltage range relative to the target output specifications. Evaluate the need for clock synchronization if multiple controllers operate in proximity to prevent sub-harmonic oscillation.

DC DC Switching Controllers Part Context

This part belongs to the TPS40090 family of multiphase controllers, designed for efficient power conversion in demanding digital loads. It serves as a central control element in complex power architectures, coordinating gate drivers to manage high-amperage transitions while maintaining stability across varying load conditions.

DC DC Switching Controllers Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio that offer similar channel counts and current capabilities. Verify that any substitute maintains compatibility with existing gate driver interfaces and control loop compensation networks.
