Overview
The BD9703CP-V5E2 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 supports a maximum output current of 1.5 A at a switching frequency of 300 kHz. It utilizes a BICMOS process for low operating current consumption. The component is housed in a TO-220-5 package and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates a Pch MOS FET switch for high efficiency in small load areas
- Utilizes Bi-CMOS process technology to achieve low operating and standby currents
- Supports PWM operation for simple step-down voltage regulation
Applications
- Industrial equipment power supplies
- Consumer electronics DC-DC conversion
- General-purpose embedded system power management
Procurement Notes
Verify the specific suffix E2 for RoHS compliance status before procurement. Confirm package type TO-220-5 matches thermal requirements. Check manufacturer lifecycle status as some variants may be discontinued. Ensure design-in documentation aligns with official datasheet specifications for electrical parameters.
Selection Notes
Select this component for applications requiring a single-output buck converter with integrated power switching. The TO-220-5 package suits through-hole mounting needs. Consider the 1.5 A current limit and 35 V input maximum when designing the power stage. Verify compatibility with external passive components for the desired output voltage setting.
Part Context
This part belongs to the BD9703 series of single-chip switching regulators. It shares core electrical characteristics with other packages in the family, such as the FP and T variants, but differs in physical mounting style. The CP-V5 designation specifically indicates the TO-220 form factor suitable for higher power dissipation scenarios compared to surface-mount options.
