Overview
The BD9701FP-E2 is a single-channel step-down switching regulator manufactured by ROHM Semiconductor. It operates with an input voltage range of 8 V to 35 V and provides an adjustable output voltage from 1 V to 32 V. The device delivers a maximum switching current of 1.5 A at a fixed switching frequency of 300 kHz. It features a built-in power MOSFET and is housed in a TO-252-5 package. The component supports shutdown functionality and maintains a load regulation of 10 mV.
Feature Summary
- Integrates a P-channel power MOSFET for high efficiency
- Adjustable output voltage via external resistor divider
- Includes shutdown control pin for power management
Applications
- Automotive infotainment systems
- On-board navigation units
- Digital cockpit displays
Procurement Notes
Verify the RoHS compliance status and REACH SVHC declarations directly through official manufacturer documentation before integration. Confirm that the specific suffix matches the required automotive qualification standards. Check for obsolescence notices as distribution channels may vary. Ensure the ordering information aligns with the exact package variant needed for your PCB layout.
Selection Notes
Select this component when a compact buck converter with integrated FET is required for automotive applications. It is suitable for designs needing 1.5 A output current within a 8 V to 35 V input window. Consider the TO-252-5 package constraints for thermal management. Compare against the BD9703FP-E2 if lower current requirements exist, or the BD9702 series for higher current needs.
Part Context
This part belongs to the BD970xFP series of simple step-down switching regulators designed for automotive use. The series integrates power MOSFETs to minimize external component count. These regulators are optimized for high efficiency and stable operation in electrically noisy automotive environments. They support standard PWM control methods for precise voltage regulation.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Verify compatibility with alternative ROHM models such as the BD9G401UEFJ-ME2 only if electrical specifications and pinouts match exactly.
