TB62754AFNG(O,EL)

Overview

The TB62754AFNG(O,EL) is an LED driver IC manufactured by Toshiba Semiconductor and Storage. It integrates a six-output DC-DC controller with step-up topology designed for PWM dimming applications. The device operates within a supply voltage range of 2.8V to 5.5V and supports a maximum output current of 48mA per channel. It utilizes a 20-pin SSOP package and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a six-output DC-DC controller with step-up topology
• Supports PWM dimming control for backlight applications
• Provides individual channel current regulation up to 48mA

Applications

• Backlight driving for mobile devices
• LCD panel illumination systems
• Portable electronic display modules

Procurement Notes

Verify the specific suffix designation against official Toshiba documentation to confirm pinout compatibility and electrical characteristics. Ensure the procurement source provides valid RoHS compliance certificates. Confirm that the component meets the required operating temperature specifications for the intended application environment before finalizing orders.

Selection Notes

Select this component when a multi-channel boost converter with integrated PWM dimming is required for LED arrays. Consider the 20-SSOP package constraints for PCB layout. Evaluate the 48mA output limit against total load requirements. Verify input voltage stability within the 2.8V to 5.5V range to ensure proper controller operation.

Part Context

This part belongs to the TB62754 series of LED driver controllers from Toshiba. It is distinct from single-output variants like the TB62755FPG. The series focuses on high-efficiency power management for display backlights. The AFNG suffix typically indicates specific packaging and environmental compliance standards defined by the manufacturer.
