BD9702T

Overview

The BD9702T is a single-channel step-down switching regulator manufactured by ROHM Semiconductor. It features an integrated Pch power MOSFET and operates within an input voltage range of 8 V to 35 V. The device provides a maximum output current of 3 A with an adjustable output voltage from 1 V to 32 V. It utilizes a fixed switching frequency of 100 kHz and supports PWM operation. The component is housed in a TO-220FP-5 through-hole package and functions across a temperature range of -40 °C to +85 °C.

Feature Summary

Integrates a Pch power MOSFET for high efficiency in small load areas
Utilizes Bi-CMOS process technology to achieve low operating current
Supports simple step-down topology with built-in controller

Applications

Industrial equipment power supplies
General-purpose DC-DC conversion circuits
Embedded system voltage regulation

Procurement Notes

Verify the specific suffix (e.g., T, T-V5) against the datasheet to confirm pinout and thermal pad configuration. Confirm RoHS compliance status as manufacturing processes may vary. Check end-of-life notifications since this series has been subject to discontinuation notices. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when a robust through-hole solution is required for currents up to 3 A. The integrated Pch FET simplifies design compared to external synchronous rectifiers. Consider thermal dissipation requirements due to the linear regulator-like behavior at light loads if not utilizing proper switching techniques. Verify that the 100 kHz frequency aligns with EMI constraints.

Part Context

This part belongs to the BD970x series of simple step-down switching regulators. It shares architectural similarities with the BD9701 and BD9703 models but offers higher current capacity. The series is designed for applications requiring cost-effective, single-channel voltage regulation with minimal external component count.
