TPS65216D0RSLR PMIC for ARM Cortex-A8/A9 SOCs | TI VQFN-48
MPN: TPS65216D0RSLR ✓ فعالTPS65216D0RSLR نمای کلی
A PMIC (Power Management Integrated Circuit) is a mixed-signal IC that combines multiple DC-DC converters, LDOs, sequencers, voltage monitors, and supervisory logic into one package. Within the broader taxonomy, a PMIC belongs to the power management semiconductor category, which itself falls under analogue and mixed-signal ICs. Modern PMICs are essential for systems-on-chip designs because they shrink the power-section footprint, reduce quiescent losses and guarantee deterministic rail sequencing during power-up, power-down and fault events.
Key features of the TPS65216 include up to three step-down DC-DC converters (each up to 2 A peak), two LDOs, power-good / reset logic, and programmable output voltages set by I2C or external feedback resistors. The wide 3.6 V to 5.5 V input range allows the device to run directly from a single-cell Li-ion battery, a 5 V USB rail or a regulated intermediate bus. The 48-pin VQFN package includes an exposed thermal pad to keep the junction temperature under control when the converters deliver full output current.
Architecturally, the TPS65216D0 (the D0 silicon revision) integrates a synchronous buck topology with internal MOSFETs and uses an internal bandgap reference plus per-rail feedback to hit output accuracies within a few percent. Built-in protection such as over-current, over-temperature, and under-voltage lockout makes it robust for industrial and consumer SBC designs. The PMIC also supports DDR-memory power requirements, including the VPP and VTT rails demanded by LPDDR/DDR memories paired with the host processor.
Typical applications include industrial automation controllers, Sitara AM335x/AM437x SBCs, FPGA-based vision and motor-control boards, and portable ARM-based test instruments. The wide input range and integrated sequencing make it especially valuable in any design where the system must start cleanly on a single lithium cell while still powering a multi-rail processor.
A key design consideration is decoupling: place a 1 µF ceramic input capacitor and per-output ceramic capacitors as close as possible to the device pins to keep ripple below the level visible to the host SOC. Always tie the exposed pad to a continuous ground plane for thermal relief, especially when drawing full converter current.

Sitara AM335x Industrial SBC
The TPS65216D0RSLR is the reference PMIC for Sitara AM335x/AM437x SBCs because its 3 integrated buck outputs (CORE, MPU, MEM) and 2 LDOs cover the AM335x voltage rail map from a single 3.6-5.5 V input. With the AM335x drawing up to ~500-800 mA on its MPU rail under load, the TPS65216's per-rail buck capability avoids discrete point-of-load regulators. Pair the IC with a 22 µF ceramic on each output to meet the AM335x ripple tolerance and sequence the rails using the EN pins.

ARM Cortex-A8 SoC Power Tree
The TPS65216D0RSLR integrates the entire power tree for ARM Cortex-A8/A9 SoCs that draw from a 5 V system bus. The 48-pin VQFN keeps the supply section under 36 mm² of board area; the exposed thermal pad spreads converter dissipation into the inner layer ground plane. With built-in RESETn and PGOOD, the host SoC sees clean rails on cold start, which is critical for booting Linux/Android without watchdog events.

FPGA-Based Vision and Motion Boards
For FPGA co-processor designs that pair an ARM Cortex host with a mid-density FPGA, the TPS65216D0RSLR supplies the FPGA's core, I/O, and auxiliary rails and the DDR memory terminations from a single 5 V input. The 3.6-5.5 V input range lets the board share a single Li-ion charger with the FPGA subsystem, while the integrated power-good signal feeds the FPGA's PWRMGT input for coordinated power-up.
پیشنهادی
Portable ARM-Based Test & Measurement
The TPS65216D0RSLR's wide 3.6-5.5 V input makes it ideal for handheld or battery-powered test instruments that pair an ARM Cortex-A host with precision ADC front-ends. With battery voltage dipping toward 3.6 V as the cell discharges, the regulator still keeps the host in regulation and avoids measurement drift. The 48-pin VQFN occupies minimal board area so designers can dedicate space to the analog front-end rather than the power section.
پیشنهادی
Industrial Automation Controllers
In factory automation, the TPS65216D0RSLR powers the Sitara-based main controller that orchestrates motor drives and fieldbus nodes from a 24 V → 5 V intermediate bus. Industrial -40 °C to +105 °C rating suits edge-mounted enclosures, while the integrated thermal shutdown protects the controller under locked-rotor motor faults where the MPU rail demands transient bursts of current.
پیشنهادی
IoT Gateway / Edge Computing Node
IoT gateways running Linux on a Cortex-A8/A9 host use the TPS65216D0RSLR as a single-chip power solution that converts a 5 V PoE or DC source into the SoC's required core, memory and I/O rails. The wide 3.6-5.5 V input permits battery-backed operation during AC outages, while I2C programmability allows the gateway to cap inrush during cold boot - critical for sealed enclosures with limited thermal headroom.

یادداشت‌های طراحی
Estimated: at VIN=5 V with all three bucks delivering rated load, total internal dissipation is around 1-2 W depending on output voltages. The 48-pin VQFN's exposed thermal pad carries heat into the inner-layer ground plane; stitch the pad with a 4×4 array of 0.3 mm thermal vias to a continuous bottom-layer ground pour to keep θJA near the manufacturer's 30 C/W range. Without thermal vias, junction temperature can rise sharply at full load.
Place the input bulk capacitor (at least 22 µF X7R ceramic plus a 47 µF tantalum bulk) directly at the VIN pins and place per-output ceramic capacitors within 2 mm of the VOUT pins to keep high-frequency ripple below the buck's loop bandwidth. Lay out the LX switch-node traces on the top layer and avoid routing analog feedback (FB_BUCKx, FB_LDOx) near the switch node to prevent noise injection into the regulation loop.
Estimated: do not float the exposed thermal pad - it serves as the main ground return and heatsink. Always populate the bootstrap capacitor (BSTx) on the correct buck, otherwise the high-side FET never drives and the regulator stalls. When sequencing multiple rails, follow the datasheet's ENx timing diagram exactly; reversing EN order can cause the host SoC to brown-out during power-up.
