TPS40200DRBT

DC DC Switching Controllers Overview

The TPS40200DRBT is a wide-input non-synchronous buck DC/DC controller manufactured by Texas Instruments. It operates within an input voltage range of 4.5V to 52V and supports output voltages from 700mV to 46V. The device features a switching frequency range of 35kHz to 500kHz with a maximum duty cycle of 95%. It provides an output current capability of 3A and consumes 1.5mA of operating supply current. The component functions in temperatures between -40°C and +85°C and is housed in an 8-SON package.

DC DC Switching Controllers Feature Summary

• Voltage-mode feedback operation with integrated feed-forward input voltage compensation for immediate response to input changes
• Integrated 200mA P-channel FET driver that disables current once the external FET is fully on to reduce power consumption
• Single external component programming for clock frequency, soft start, and overcurrent limit settings
• External synchronization capability to align with other controllers or system clocks for sequencing and noise reduction

DC DC Switching Controllers Applications

• Industrial control systems requiring wide input voltage ranges
• Automotive electronics applications
• Distributed power architectures
• Point-of-load regulation modules

DC DC Switching Controllers Procurement Notes

Verify the specific suffix DRBT corresponds to the 8-SON package configuration when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the selected variant meets the required thermal management specifications for the intended operating environment. Cross-reference the datasheet revision to ensure compatibility with existing design parameters.

DC DC Switching Controllers Selection Notes

Select this controller for designs requiring a wide input voltage range up to 52V without synchronous rectification. The device is suitable for applications needing programmable switching frequencies and precise low-voltage regulation via the 700mV reference. Consider the 8-SON package constraints for PCB layout and thermal dissipation requirements during the selection process.

DC DC Switching Controllers Part Context

This component belongs to the TPS40200 family of wide-input-range non-synchronous voltage-mode controllers. It is designed for high-efficiency power conversion in demanding environments. The series offers flexibility through external programming options and robust protection features, making it a versatile choice for various DC/DC converter topologies.

DC DC Switching Controllers Replacement Considerations

The TPS40200DRBR serves as a pin-compatible alternative within the same family, differing primarily in the SOIC-8 package instead of the SON-8 form factor.
