Ultra-small RGB LED animation solution reference design for battery-operated applications

TIDA-050013

Overview

This reference design is a 2cm x 2cm RGB LED animation solution for battery powered applications using the LP5523 and MSP430FR2111 devices. The LP5523 device is an LED driver with a programmable control engine in a DSBGA package. The LP5523 provides realistic lighting patterns for applications that must fit on extremely small PCBs. The design demonstrates full functionality while using limited MCU resources.

characteristic

● Minimum MCU load when running preset lighting patterns
● Lower system current consumption can be achieved through LP5523 engine control
● Low quiescent current during standby mode
● Comprehensive diagnosis and protection
● 2cm² small PCB size design
