Product details
Overview
TPS562212DRLR from Texas Instruments is a synchronous buck DC-DC converter delivering up to 2-A continuous output current across 0.6-V to 7-V output voltages from a 4.2-V to 18-V input rail, featuring integrated 66-mΩ high-side and 33-mΩ low-side MOSFETs, 45-ns minimum on-time, and 98% maximum duty cycle-used in smart speaker power rails and wired networking point-of-load regulation.
For engineers reviewing the TPS562212DRLR datasheet, TPS562212DRLR pinout, TPS562212DRLR application, or TPS562212DRLR equivalent, key selection criteria include Eco-mode/FCCM configurability via MODE pin, selectable PG/SS function, ±1% reference accuracy at 25°C, internal compensation for minimal external components, and SOT-5X3 (8-pin) thermal performance with RθJA = 116.7°C/W.
Technical Context
The TPS562212DRLR implements Advanced Emulated Current Mode (AECM) control, combining peak current mode stability with D-CAP2-like transient response while maintaining true fixed 1.2-MHz switching frequency. Its dual-cycle current limiting monitors both high-side peak (3.5-A typical) and low-side valley (2.6-A typical) currents for robust overload protection.
Operation mode (Eco-mode vs FCCM) and PG/SS pin function are jointly configured via a single MODE pin resistor, enabling flexible light-load efficiency optimization and either power-good indication or adjustable soft-start-without requiring additional control logic or external timing components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.2 V to 18 V - supports common industrial and consumer rails including 12 V and 15 V without pre-regulation. |
| Output Voltage Range | 0.6 V to 7 V - covers core logic, I/O, and analog supply requirements for SoCs and FPGAs. |
| Max Output Current | 2 A continuous - sufficient for mid-power digital subsystems like STB mainboard SoC cores or network PHYs. |
| Switching Frequency | 1.2 MHz (±8.5%) - enables compact magnetics and EMI filtering with predictable spectral content. |
| Quiescent Current | 120 µA typical in Eco-mode - extends battery life in always-on smart speaker standby states. |
| Reference Accuracy | ±1% at 25°C - ensures tight output regulation critical for memory and processor voltage margins. |
| Min On-Time | 45 ns - supports high step-down ratios (e.g., 12 V → 1.05 V) without pulse-skipping instability. |
| Duty Cycle Max | 98% - enables operation down to ~4.3 V input when regulating 4.2 V output, improving dropout margin. |
Pinout & Package
The TPS562212DRLR is housed in an 8-pin SOT-5X3 (DRL) package measuring 1.6 mm × 2.1 mm with 0.4-mm pitch, optimized for high-density PCB layouts and thermal performance (RθJB = 20.9°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PG/SS (Pin 1) | I/O | Configurable as open-drain power-good indicator (with pull-up) or soft-start timing node (external capacitor to GND); function selected by MODE resistor. |
| VIN (Pin 2) | Power | Main input supply for control circuitry and high-side gate driver; requires local decoupling to GND. |
| SW (Pin 3) | Power | Switch node connecting internal HS/LS MOSFETs to external inductor; carries high di/dt and must be routed short and wide. |
| GND (Pin 4) | Ground | Common return for controller, gate drivers, and feedback network; must connect to low-impedance ground plane. |
| BOOT (Pin 5) | Power | High-side gate drive supply; requires 0.1-µF ceramic capacitor between BOOT and SW for charge pump operation. |
| EN (Pin 6) | I/O | Enable control with precise 1.15-V rising threshold; supports adjustable VIN UVLO using external resistor divider. |
| MODE (Pin 7) | I/O | Configures light-load mode (Eco/FCCM) and PG/SS function via resistor-to-GND; latched after startup. |
| FB (Pin 8) | Input | Feedback input sensing output voltage via resistor divider; sets regulated VOUT with ±1% reference accuracy. |
Key Features
| Feature | Design Value |
|---|---|
| Advanced Emulated Current Mode (AECM) | Delivers fast transient response across full 0.6–7-V output range without external compensation components. |
| Selectably Configured Light-Load Operation | Eco-mode (PFM) for ultra-low IQ or FCCM for fixed-frequency noise control-set via single MODE resistor. |
| Dual-Stage Overcurrent Protection | High-side peak current limit (3.5 A typ) + low-side valley current limit (2.6 A typ) prevent runaway under overload and short-circuit. |
| Non-Latching Fault Protections | OVP, UVP, UVLO, and thermal shutdown (150°C) enter hiccup mode (6-cycle restart delay), minimizing stress during faults. |
| Integrated Power-Stage MOSFETs | 66-mΩ HS + 33-mΩ LS RDS(on) enable high-efficiency 2-A operation in ultra-small SOT-5X3 footprint. |
| Precise Enable & Adjustable UVLO | EN pin with 1.15-V threshold and internal pullup allows simple enable control or programmable VIN UVLO using two resistors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS562201DRLR | 1.5-A rated, identical SOT-5X3 package and pinout; shares same AECM control and MODE/PG-SS architecture but lower current capability. | Suitable for sub-1.5-A loads where board space and BOM reuse are prioritized over headroom. | Select when output current demand is ≤1.5 A and cost sensitivity outweighs need for 2-A margin. |
| MP2315GJ-Z | 2-A rating, 4.5–18-V input, 1.2-MHz fixed frequency, but uses peak current mode (not AECM); no MODE-configurable Eco/FCCM or PG/SS duality. | Requires external compensation and lacks soft-start adjustability; better suited for cost-driven, non-critical timing applications. | Choose only if AECM transient performance and dual-function pin flexibility are not required and MP2315's simpler feature set suffices. |
Compared with TPS562201DRLR, the TPS562212DRLR provides 33% higher output current headroom in identical footprint; versus MP2315GJ-Z, it delivers superior light-load efficiency control, integrated soft-start adjustment, and simplified loop design via internal compensation-justifying its use in noise-sensitive, thermally constrained, or dynamically loaded systems.

FAQ
What is the maximum continuous output current supported by the TPS562212DRLR?
The TPS562212DRLR supports up to 2-A continuous output current across its full 0.6-V to 7-V output voltage range, verified under recommended operating conditions (TJ ≤ 125°C, proper PCB thermal design). This rating assumes adequate board-level copper area and airflow; actual achievable current depends on ambient temperature, input voltage, and output voltage configuration.
Does the TPS562212DRLR require external compensation components?
No, the TPS562212DRLR features internal compensation enabled by its Advanced Emulated Current Mode (AECM) control architecture. This eliminates the need for external Type-II or Type-III compensation networks, reducing BOM count and simplifying layout-while still delivering fast transient response across the entire 0.6-V to 7-V output range.
How is the power-good (PG) function configured on the TPS562212DRLR?
The power-good function on the TPS562212DRLR is configured via the MODE pin: connecting MODE to GND selects Eco-mode with PG enabled on the PG/SS pin (Pin 1), which operates as an open-drain output requiring a 10-kΩ pull-up to ≤5.5 V. The PG signal asserts high after VOUT reaches 92–112% of target and remains valid for >112 µs, deasserting within 48 µs if VOUT falls outside UVP/OVP thresholds.
What is the minimum input voltage required for the TPS562212DRLR to maintain valid power-good output?
The TPS562212DRLR requires a minimum VIN of 2.5 V to sustain valid power-good (PG) output on the PG/SS pin. Below this level, PG behavior becomes undefined per datasheet specifications. This threshold ensures sufficient headroom for internal bias generation and reliable comparator operation during brownout conditions.
Can the TPS562212DRLR operate in forced continuous conduction mode (FCCM)?
Yes, the TPS562212DRLR supports FCCM operation, selectable via the MODE pin: leaving MODE floating configures FCCM with PG function on PG/SS, while connecting MODE to 100-kΩ resistor to GND selects FCCM with external soft-start. FCCM ensures constant 1.2-MHz switching frequency across all load conditions, eliminating audible noise and simplifying EMI filtering compared to Eco-mode's variable-frequency PFM operation.
