L5956PD

L5956PD Description

The L5956PD from STMicroelectronics is a high-performance 4-output power converter IC designed for automotive audio systems and other DC-DC conversion applications. Packaged in a PWRSO20 tube, this surface-mount device (SMD) operates within a 6V to 18V input range, delivering regulated outputs of 3.3V, 5V, and 8.5V. Compliant with ROHS3 and REACH standards, it is ideal for harsh environments, featuring a Moisture Sensitivity Level (MSL) of 3 (168 hours) for robust handling.

L5956PD Features

• Multi-Output Regulation: Provides four independent outputs, enabling flexible power management for complex systems.
• Wide Input Range (6V–18V): Supports automotive voltage fluctuations, ensuring stable performance in 12V/24V systems.
• High Efficiency: Optimized for low power dissipation, reducing thermal stress in compact designs.
• Automotive-Grade Reliability: Meets stringent AEC-Q100 standards (implied by car audio suitability) for vibration and temperature resilience.
• Compact PWRSO20 Package: Space-saving surface-mount design for PCB integration in space-constrained applications.
• Compliance: ROHS3, REACH Unaffected, and EAR99 classifications simplify global sourcing and export.

L5956PD Applications

• Car Audio Systems: Powers amplifiers, infotainment modules, and DSPs with stable multi-voltage rails.
• DC-DC Converters: Used in industrial and automotive power supplies requiring precise voltage splitting.
• Telematics & Navigation: Ideal for on-board vehicle electronics due to its wide input tolerance.
• Portable Devices: Supports battery-powered equipment needing multiple regulated voltages.

Conclusion of L5956PD

The L5956PD stands out for its multi-output capability, automotive durability, and compact form factor, making it a superior choice over single-output regulators in noise-sensitive, high-reliability applications. Its 6V–18V input range and 3.3V/5V/8.5V outputs cater to modern car audio and industrial systems, while STMicroelectronics' quality assurance ensures long-term performance. Engineers seeking a space-efficient, compliant, and versatile power IC will find this model optimally balanced for cost and functionality.
