Special Purpose Regulators

TPS65218B1PHPT Description

The TPS65218B1PHPT from Texas Instruments is a highly integrated power management IC (PMIC) designed for ARM Cortex-A8/A9-based applications. This 7-output regulator combines multiple voltage rails into a single compact solution, supporting input voltages from 2.2V to 5.5V. Packaged in a 48-pin HTQFP and available in Tape & Reel (TR), it is optimized for surface-mount assembly. Though marked as Not For New Designs, it remains a reliable choice for legacy systems requiring robust power management. The device complies with ROHS3 and REACH environmental standards, with a Moisture Sensitivity Level (MSL) of 3 (168 hours).

TPS65218B1PHPT Features

• Multi-Output Integration: Seven regulated outputs minimize external components, reducing PCB footprint and BOM cost.
• Wide Input Range (2.2V–5.5V): Supports diverse power sources, including Li-ion batteries and regulated DC supplies.
• Optimized for ARM Processors: Tailored for Cortex-A8/A9 cores, ensuring stable voltage sequencing and low noise.
• High Efficiency: Switching regulators and LDOs maximize power efficiency for battery-sensitive applications.
• Robust Protection: Features overcurrent, overtemperature, and undervoltage lockout (UVLO) safeguards.
• Industry-Standard Compliance: ROHS3, REACH Unaffected, and EAR99 classifications ensure global usability.

TPS65218B1PHPT Applications

• Embedded Systems: Ideal for industrial control, IoT gateways, and single-board computers (SBCs) using ARM Cortex-A8/A9.
• Portable Electronics: Suited for handheld devices, medical monitors, and battery-powered equipment requiring multi-rail power.
• Legacy Designs: Maintains power integrity in existing products where redesigns are impractical.
• Automotive Infotainment: Supports secondary power management in dashboards and telematics (non-safety-critical).
