BD9778HFP-TR

Overview

The BD9778HFP-TR is a non-synchronous buck switching regulator IC manufactured by Rohm Semiconductor. It features an input voltage range of 7V to 35V and delivers a maximum output current of 2A. The device provides a single positive adjustable output, configurable from 1V up to the input voltage level using external resistors. The internal switching frequency is adjustable between 50kHz and 500kHz via external components. It operates within a temperature range of -40°C to 125°C and utilizes an HRP-7 package with seven leads and a tab for thermal dissipation.

Feature Summary

Integrates a P-channel power MOSFET and controller in a single non-synchronous topology
Supports wide input voltage operation suitable for industrial applications
Allows flexible configuration of output voltage and switching frequency through external passive components

Applications

Industrial equipment power supplies
General purpose DC/DC conversion systems
Embedded control circuits requiring wide input ranges

Procurement Notes

Verify component authenticity and datasheet revisions prior to integration. Confirm that the HRP-7 package dimensions align with the target PCB footprint. Ensure thermal management strategies account for the junction temperature limits specified in the official documentation. Validate that the selected switching frequency and output voltage settings remain within the operational boundaries defined by the manufacturer.

Selection Notes

Select this component when a non-synchronous buck converter is required for high-current applications with wide input voltage variations. Consider the adjustable frequency feature for optimizing electromagnetic interference profiles. Evaluate the thermal performance characteristics of the HRP-7 package against the expected load conditions. Ensure compatibility with the desired output voltage range and current requirements for the specific circuit design.
