BD9701CP-V5E2

Overview

The BD9701CP-V5E2 is a single-channel step-down switching regulator manufactured by ROHM Semiconductor. It operates with an input voltage range of 8V to 35V and provides an adjustable output voltage from 1V to 32V. The device supports a maximum switching current of 1.5A and utilizes a non-synchronous buck topology. It features a built-in Pch MOS FET for high efficiency in small load areas. The component is housed in a TO-220CP-V5 package and is designed for surface mount or through-hole installation depending on the specific variant configuration.

Feature Summary

• Integrates a Pch power MOSFET to ensure high efficiency across various load conditions
• Utilizes Bi-CMOS process technology to achieve low operating current and zero standby current
• Provides simple step-down regulation capability with built-in protection circuits

Applications

• General purpose DC-DC conversion in industrial equipment
• Power supply stages for consumer electronics devices
• Embedded systems requiring stable voltage regulation from higher input rails

Procurement Notes

Verify the exact ordering suffix and package type against the official datasheet, as variations exist within the BD9701 series. Confirm availability status as this component may be subject to end-of-life notices or discontinuation. Ensure compatibility with your PCB footprint requirements for the TO-220CP-V5 package before finalizing procurement decisions.

Selection Notes

Select this component when a robust, single-output buck converter is needed with integrated power switching. It is suitable for applications requiring input voltages up to 35V and output currents up to 1.5A. Consider thermal management requirements due to the through-hole package style and power dissipation characteristics inherent to linear or switching regulators in this form factor.

Part Context

This part belongs to the BD9701/BD9703/BD9702 series of single-chip type switching regulators with built-in FETs. These components are designed for PWM operation and offer simplified design processes by integrating the controller and power switch. The series emphasizes low electricity consumption and compact solution sizes for various power management needs.

Replacement Considerations

Direct substitutes include BD9701FP-E2 (TO-252-5 package) and BD9701T (TO-220FP-5 package). Verify pinout compatibility and thermal performance differences between the CP-V5 and other package variants before substitution.
