Product details
Overview
TPS65216D0RSLR from Texas Instruments is a highly integrated power management IC (PMIC) designed for AMIC110/AMIC120/AM335x/AM437x processors in 5V line-powered industrial systems. It delivers four DC/DC converters (three 1.8A buck, one 1.6A buck-boost), one 400mA adjustable LDO, integrated power sequencing, and I²C programmability - enabling full core, MPU, DDR, analog I/O, and peripheral rail control in a single 48-pin VQFN package.
For engineers reviewing the TPS65216D0RSLR datasheet, TPS65216D0RSLR pinout, TPS65216D0RSLR application, or TPS65216D0RSLR equivalent, this page provides verified technical context, validated pin functions, confirmed sequencing behavior, real-world industrial use cases, and two rigorously cross-checked alternative PMICs for AM335x/AM437x-based designs.
Technical Context
The TPS65216D0RSLR implements three hysteretic step-down converters (DCDC1–DCDC3) with dynamic voltage scaling and programmable slew rates for processor core/MPU/DDR rails, plus a buck-boost converter (DCDC4) for 3.3V analog/I/O. All five regulators feature ±4–5% supervisor tolerance, active output discharge, and I²C-configurable power-up/down sequences.
Its integrated supervisor monitors DCDC1–DCDC4 and LDO1 with dual STRICT modes (±4% or ±0.25% hysteresis), while protection includes UVLO, overtemperature warning/shutdown (135°C trip), push-button monitoring, and interrupt reporting via nINT. The I²C interface (address 0x24) supports 400kHz operation with strict timing compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| DCDC1–DCDC3 Output Current | 1.8A continuous per rail - sufficient to power AM335x core, MPU, and DDR3 memory simultaneously. |
| DCDC4 Output Current | 1.6A at 5V input - supports high-current 3.3V analog and I/O domains without external boost circuitry. |
| LDO1 Output Current | 400mA max - delivers stable 1.8V for processor analog peripherals and I/O banks. |
| Input Voltage Range | 2.7V–5.5V for DC/DC rails; 1.8V–10V for load switch - compatible with standard 5V industrial supply rails and backup battery inputs. |
| Operating Temperature | –40°C to +105°C - qualified for extended industrial environments including factory automation and grid infrastructure. |
| I²C Address | Fixed 0x24 - enables deterministic system-level configuration without address conflict in multi-PMIC designs. |
| Package | 48-pin VQFN (6mm × 6mm, 0.4mm pitch) with exposed thermal pad - supports high-power density PCB layouts with efficient thermal dissipation. |
Pinout & Package
TPS65216D0RSLR uses a 48-pin RSL VQFN package (6mm × 6mm, 0.4mm pitch) with exposed thermal pad connected to GND for thermal relief and power ground integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN_DCDC1–IN_DCDC4, IN_LDO1, IN_LS | Power input terminals | Dedicated input pins per regulator/switch - enable independent supply routing and noise isolation between rails. |
| FB1–FB3, FB4 (via DCDC4 pin) | Feedback inputs | Resistor-divider nodes for precise output voltage regulation; each tied directly to respective output capacitor. |
| L1–L4A/L4B, L3 | Switch node terminals | High-current paths connecting internal FETs to external inductors - require short, low-inductance PCB traces. |
| PGOOD | Open-drain power-good indicator | Asserts low if any of DCDC1–DCDC4 or LDO1 falls outside ±4–5% regulation - used for system boot sequencing validation. |
| SDA/SCL, nINT, GPIO1/GPIO2 | I²C and configurable I/O | Enable firmware-controlled power state transitions, warm reset (GPIO2), and interrupt-driven fault response. |
Key Features

FAQ
What is the default output voltage of DCDC1 in the TPS65216D0RSLR?
The TPS65216D0RSLR has a factory-default output voltage of 1.1V for DCDC1, adjustable via I²C register writes across a 0.85V–1.675V range. This default setting aligns with the nominal core voltage requirement of AM335x and AM437x processors during initial boot, and can be dynamically scaled during runtime for power optimization.
Does the TPS65216D0RSLR support dynamic voltage scaling for processor cores?
Yes, the TPS65216D0RSLR supports dynamic voltage scaling (DVS) on DCDC1 and DCDC2 through I²C-controlled output voltage adjustment and programmable slew rates. This allows the TPS65216D0RSLR to track processor frequency changes in real time, reducing dynamic power consumption while maintaining stability during voltage transitions.
How does the TPS65216D0RSLR handle power sequencing for AM335x processors?
The TPS65216D0RSLR implements fully programmable power sequencing via I²C registers, enabling precise control over the enable/disable order and timing delays for all five regulators. For AM335x processors, this ensures DCDC3 (DDR) remains powered during SUSPEND mode while DCDC1/DCDC2 (core/MPU) are safely ramped down - matching the exact requirements defined in the AM335x Technical Reference Manual.
What is the maximum current rating of the load switch in the TPS65216D0RSLR?
The TPS65216D0RSLR load switch supports up to 900mA continuous output current when VIN_LS > 2.3V and LSILIM[1:0] = 11b, with a maximum RDS(on) of 440mΩ at 9V input. Its selectable current limit (100/200/500/900mA) and internal discharge resistor allow safe, configurable power delivery to auxiliary subsystems without external current-sense circuitry.
Is the TPS65216D0RSLR compatible with the AM437x processor family?
Yes, the TPS65216D0RSLR is explicitly designed and characterized for use with the AM437x processor family, powering its core (DCDC1), MPU (DCDC2), DDR3 (DCDC3), 3.3V analog/I/O (DCDC4), and 1.8V analog peripherals (LDO1). TI confirms full functional and timing compatibility across the –40°C to +105°C operating range specified for AM437x industrial applications.
