BP5326

Special Purpose Regulators Overview

The BP5326 is a specialized LCD converter voltage regulator IC manufactured by Rohm Semiconductor. It features a single output configuration housed in a 9-SIP package with seven leads. Designed for specific power management applications, this component converts input voltages to a regulated output range of 28 V to 31 V. The device supports a maximum output current of 0.025 A and operates as a switching voltage regulator. It is suitable for through-hole mounting and complies with RoHS standards, serving as a dedicated solution for LCD bias generation in electronic systems.

Special Purpose Regulators Feature Summary

• Single-output LCD converter voltage regulation
• Dedicated switching regulator topology for display biasing
• Through-hole compatible SIP packaging

Special Purpose Regulators Applications

• LCD panel bias voltage generation
• Display driver power supply circuits
• Specialized industrial control panels requiring stable LCD operating voltages

Special Purpose Regulators Procurement Notes

Verify the exact package variant (9-SIP) and lead configuration against the target PCB footprint before procurement. Confirm that the required output voltage falls within the specified 28 V to 31 V range for the specific application load. Ensure thermal management strategies are adequate for the through-hole mounting style and expected ambient operating conditions.

Special Purpose Regulators Selection Notes

Select this component when a dedicated, high-voltage linear or switching regulator is not suitable for generating precise LCD bias voltages. It is appropriate for designs requiring a fixed, regulated output from a higher input rail specifically for display technologies. Consider the 0.025 A current limit to ensure it meets the total capacitive and leakage load requirements of the LCD module without exceeding the device's rating.

Special Purpose Regulators Part Context

This part belongs to Rohm’s portfolio of special-purpose regulators, distinct from general-purpose PMICs. It addresses niche requirements in display electronics where standard voltage regulators lack the necessary output voltage range or form factor. The 9-SIP package allows for easy integration into legacy or space-constrained through-hole designs common in industrial and consumer display equipment.

Special Purpose Regulators Replacement Considerations

Direct substitutes must match the 9-SIP package, 28-31 V output range, and 25 mA current capability. Verify pin compatibility for through-hole assembly. Alternative LCD bias generators may require external components if they do not integrate the full conversion function.
