Overview
The BD9702CP-V5E2 is a single-channel step-down switching regulator manufactured by ROHM Semiconductor. It utilizes PWM operation with a built-in Pch MOS FET to ensure high efficiency in small load areas. The device supports an input voltage range from 8V to 35V and provides an adjustable output voltage between 1V and 32V. It delivers a maximum switching current of 3A at a typical switching frequency of 300kHz. Operating temperatures range from -40°C to 85°C, and it is housed in a TO-220CP-V5 package.
Feature Summary
- Built-in Pch MOS FET for high efficiency
- Adjustable output voltage capability
- Low operating and standby current consumption
Applications
- General purpose power supplies
- Industrial equipment
- Consumer electronics
Procurement Notes
Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm the specific suffix matches the required package and temperature grade. Check for end-of-life status or obsolescence notices before finalizing procurement plans. Ensure thermal management solutions align with the TO-220CP-V5 package characteristics.
Selection Notes
Select this component when a 3A buck converter with adjustable output is required. Consider the TO-220CP-V5 package for through-hole mounting applications. Evaluate thermal dissipation requirements based on the expected load current and ambient temperature conditions. Verify compatibility with external feedback resistors for the desired output voltage setting.
Part Context
This part belongs to the BD9701/BD9703/BD9702 series of single-chip type switching regulators with built-in FETs. These devices are designed as simple step-down switching regulators using Bi-CMOS process technology. The series aims to reduce electricity consumption through low operating current and zero standby current typical values.
Replacement Considerations
The BD9701CP-V5E2 offers similar functionality but with a lower 1.5A current rating. The BD9703CP-V5E2 also provides 1.5A output. For higher current needs, verify if the BD9702FP variant meets surface-mount requirements instead.
