Overview
The BD9009HFP-TR is a step-down switching voltage regulator IC manufactured by ROHM Semiconductor. It operates with an input voltage range of 7V to 35V and provides a maximum output current of 4A. The device features an adjustable output voltage starting from 0.8V, offering flexibility for various power supply designs. It utilizes the HRP-7 package, which consists of seven leads plus a tab, suitable for surface-mount applications. This component is classified as a DC-DC converter within the power management integrated circuit category.
Feature Summary
- Integrates a synchronous buck converter topology for efficient step-down voltage conversion
- Supports adjustable output voltage regulation via external resistor network
- Designed for high-current delivery up to 4A in a compact surface-mount footprint
Applications
- Portable electronic devices requiring stable 5V or 12V rails
- Industrial control systems utilizing 24V input sources
- Consumer electronics with battery-powered operation profiles
Procurement Notes
Verify the specific suffix and package variant against the official datasheet before ordering. Confirm lifecycle status, as this part may be marked as not recommended for new designs. Ensure compatibility with thermal requirements due to the HRP-7 package construction. Cross-reference pinouts with the manufacturer's documentation to avoid integration errors during PCB layout.
Selection Notes
Select this component when a single-output adjustable buck converter is required for inputs between 7V and 35V. Consider the 4A current capability and the HRP-7 package size for space-constrained designs. Evaluate thermal dissipation needs given the power handling capabilities. Compare efficiency characteristics at specific load points against alternative regulators in the same family.
Part Context
This part belongs to ROHM's series of switching voltage regulators designed for general-purpose power management. It falls under the broader category of DC-DC converters used in portable and industrial equipment. The HRP-7 package is commonly used for medium-power applications requiring good thermal performance. It serves as a solution for converting higher bus voltages to lower logic or peripheral supply levels.
Replacement Considerations
Check for direct pin-compatible substitutes within the ROHM BD90xx series. Verify if newer revisions offer improved efficiency or different packaging options. Ensure that any replacement maintains the 4A current rating and 35V maximum input voltage specification. Consult the manufacturer's obsolescence notices for recommended alternatives.
