Overview
The BD9701T-V5 is a single-channel step-down switching regulator from Rohm Semiconductor, designed for non-synchronous PWM operation. It integrates a Pch MOS FET to ensure high efficiency in small load areas. The device supports an input voltage range of 8V to 35V and provides an adjustable output voltage from 1V to 32V. It delivers a maximum output current of 1.5A with a typical operating current of 4mA and standby current of 0uA. The component utilizes Bi-CMOS process technology and operates within a temperature range of -40°C to 85°C.
Feature Summary
- Integrates a Pch MOS FET for high efficiency in small load areas
- Realizes lower electricity consumption with 4mA typical operating current and 0uA typical standby current
- Adopts Bi-CMOS process technology for stable performance
Applications
- Industrial applications requiring simple step-down switching regulators
- Equipment needing reduced standby power consumption
- Systems utilizing single-chip type regulators with built-in FETs
Procurement Notes
Verify the specific suffix 'V5' against official datasheets to confirm pinout and electrical characteristics match design requirements. Confirm RoHS compliance status as per latest manufacturer documentation. Check for end-of-life or last-time-buy notices if sourcing for long-term production. Ensure thermal management aligns with TO-220FP-5 package limitations.
Selection Notes
Select this component when a non-synchronous buck converter with integrated power switch is required for moderate current loads up to 1.5A. It is suitable for designs prioritizing simplicity and low standby current over synchronous rectification efficiency. Consider the TO-220FP-5 package for through-hole mounting and heat dissipation needs compared to surface-mount alternatives.
Part Context
This part belongs to the BD9701/BD9703/BD9702 series of single-channel step-down switching regulators. These devices are characterized by their ability to perform PWM operation with built-in power MOSFETs. The series is designed to offer high efficiency and low power consumption through Bi-CMOS process integration, targeting industrial and general electronic applications.
Replacement Considerations
Check for BD9703T-V5 for similar specifications but potentially different switching frequency or current ratings. Verify BD9702T-V5 if higher output current capability around 3A is needed. Ensure any substitute maintains the same TO-220FP-5 package and voltage/current ratings.
