RT8555AWSC

Overview

The RT8555AWSC is a highly integrated, low-profile, six-channel step-up (boost) DC-DC converter designed for LED backlight applications. It features analog and PWM dimming capabilities with an input voltage range of 2.7V to 24V. The device provides up to 35mA per channel output current. It is housed in a 20-WLCSP package measuring 1.65x2.05mm.

Feature Summary

Six independent output channels for driving multiple LED strings
Supports both analog and PWM dimming control methods
Highly integrated low-profile design suitable for space-constrained devices

Applications

LED backlight drivers for mobile phones
LED backlight drivers for tablets
Portable electronic display illumination systems

Procurement Notes

Verify the specific suffix 'WSC' against the manufacturer's official datasheet to confirm pinout and thermal characteristics. Ensure the component meets RoHS compliance requirements for your target market. Confirm availability status as distribution stocks may vary.

Selection Notes

Select this component when a multi-channel boost converter is required for LCD backlighting. Consider the 20-WLCSP package size for board space limitations. Verify that the input supply voltage falls within the 2.7V to 24V operating range before integration.

Part Context

This part belongs to Richtek's portfolio of power management ICs focused on portable electronics. It serves as a specialized solution for high-density LED driving needs in consumer devices where efficiency and small form factor are critical design constraints.

Replacement Considerations

Consult the manufacturer's official substitution guide for verified alternatives. Do not assume cross-compatibility with other multi-channel boost converters without verifying electrical parameters and pin configurations.
