SKY81453-13-001

Overview

The SKY81453-13-001 is a six-channel, high-efficiency white LED driver IC manufactured by Skyworks Solutions Inc. It integrates a DC-DC step-up regulator capable of driving multiple LEDs in series or parallel configurations. The device supports analog and PWM dimming methods for precise brightness control. Communication with the host system is facilitated via an I2C interface. The component is housed in a compact 25-ball WLCSP package measuring 2.44x2.44 mm, suitable for space-constrained mobile applications.

Feature Summary

• Six independent output channels for driving white LEDs
• Integrated high-efficiency boost converter topology
• Supports both analog and pulse-width modulation dimming techniques
• I2C serial interface for configuration and control

Applications

• Mobile phone camera flash systems
• Smartphone ambient light sensing modules
• Tablet computer display backlighting
• Compact wearable device illumination

Procurement Notes

Verify the specific datasheet revision and ordering suffix to ensure compatibility with your design requirements. Confirm that the 25-ball WLCSP package dimensions align with your PCB footprint constraints. Check for any recent addendums regarding electrical characteristics or thermal performance updates from Skyworks Solutions before finalizing procurement.

Selection Notes

Select this component when designing systems requiring multi-channel LED control within a minimal footprint. The integrated boost converter simplifies power management compared to discrete solutions. Ensure the input voltage range matches your battery supply. Consider the thermal dissipation capabilities of the WLCSP package under maximum load conditions during the initial design phase.

Part Context

This part belongs to Skyworks' portfolio of LED lighting drivers designed for portable electronics. It complements other single or dual-channel drivers by offering higher channel density in a small form factor. The product line focuses on improving battery life through high conversion efficiency while maintaining accurate color consistency across multiple LED channels.

Replacement Considerations

Direct substitutes may include other Skyworks six-channel LED drivers if pinout and functionality match. Verify equivalent electrical specifications such as current limits and switching frequency. Cross-reference with competitors only if they offer identical I2C control and physical package dimensions.
