The power supply design presented unique challenges, requiring a dual-rail configuration for simplified biasing while maintaining a compact 3mm height profile. The implementation delivers 500mA current capability with adjustable regulation and comprehensive filtering stages. A 4-layer PCB design was chosen to optimize thermal management and signal integrity.
