BP5302A

Special Purpose Regulators Overview

The BP5302A is a DC/DC converter module designed for supplying power to liquid crystal display panels. It generates a negative output voltage from a positive input supply, featuring a wide input range of +5V to +14V and a high-accuracy output of -24V ±0.75V. The device offers typical conversion efficiency of 80% and includes built-in protection circuits and an ON/OFF switch. It is housed in a compact single in-line package with upright leads.

Special Purpose Regulators Feature Summary

• Generates negative voltage from positive supply for LCD panels
• Built-in protection circuitry and ON/OFF switch
• High accuracy output voltage specification
• Compact and lightweight single in-line package design

Special Purpose Regulators Applications

• LCD panels in personal computers
• LCD panels in word processors

Special Purpose Regulators Procurement Notes

Verify the specific lead type configuration required for your PCB layout, as the BP5302XA variant utilizes L-shaped leads while this model uses upright leads. Confirm that the input voltage range aligns with your system's positive supply rails before integration. Ensure thermal management considerations are addressed despite the compact form factor.

Special Purpose Regulators Selection Notes

Select this component when a dedicated negative rail is required for LCD biasing from a standard positive logic supply. Compare against the BP5302XA if space constraints necessitate an L-shaped lead orientation. Evaluate the fixed -24V output against other available voltages if different panel requirements exist.

Special Purpose Regulators Part Context

This module belongs to ROHM Semiconductor's family of DC/DC converters specifically engineered for display applications. It serves as a self-contained power solution, eliminating the need for discrete inductor and capacitor networks typically required in custom flyback or boost converter designs for generating negative LCD voltages.

Special Purpose Regulators Replacement Considerations

The BP5302XA is a direct functional substitute offering identical electrical characteristics but with L-shaped leads for different mounting orientations. Other models like the BP5319 or BP5313A provide similar functionality but may differ in output voltage or pinout configurations.
