Product details
Overview
TPS62184YZFR from Texas Instruments is a synchronous dual-phase step-down DC-DC converter delivering up to 6 A continuous output current across two balanced 3-A phases. It operates from 4 V to 17 V input, supports adjustable output voltages from 0.9 V to 3.5 V, and features Automatic Efficiency Enhancement (AEE™), phase-shifted operation, and Power Good signaling - enabling compact, low-profile POL supplies for battery-powered computing systems.
For engineers reviewing the TPS62184YZFR datasheet, TPS62184YZFR pinout, TPS62184YZFR application, or TPS62184YZFR equivalent, key selection considerations include its 24-bump DSBGA package, dual-phase peak current mode control, ±1% output voltage accuracy in PWM mode, 28 µA quiescent current, and integrated hiccup overcurrent protection.
Technical Context
The TPS62184YZFR uses predictive OFF-time peak current mode control with separate master/follower current loops, ensuring cycle-by-cycle current balancing within ±10% at full load. Its fixed 250 ns phase delay between SW1 and SW2 reduces input RMS current and switching noise in PWM mode.
It implements automatic transition between PWM and Power Save Mode (PSM) based on load, maintains 100% duty cycle operation near VIN ≈ VOUT, and employs AEE™ to dynamically adjust switching frequency - preserving high efficiency across wide VIN/VOUT ratios without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4 V to 17 V - supports multi-cell Li-ion batteries and standard 12-V rails without external pre-regulation. |
| Output Current | 6 A continuous - delivered via two 3-A phases, enabling use of low-profile 1-µH inductors and minimizing board area. |
| Output Voltage Range | 0.9 V to 3.5 V - programmable via external resistor divider; regulated to 0.8 V reference at FB pin. |
| Quiescent Current | 28 µA typical - enables ultra-low-power standby in always-on embedded systems. |
| Feedback Accuracy | ±1% in PWM mode - ensures tight regulation for sensitive core logic and memory rails. |

| Package | 24-bump DSBGA (YZF), 2.10 mm × 3.10 mm - ultra-compact footprint for space-constrained portable designs. |
Pinout & Package
The TPS62184YZFR is housed in a 24-bump, 0.5-mm pitch NanoFree™ DSBGA (YZF) package measuring 2.10 mm × 3.10 mm, optimized for low-height applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN1 / VIN2 | Phase 1 / Phase 2 input supply | Dual independent input pins reduce trace inductance per phase and improve current sharing stability. |
| SW1 / SW2 | Phase 1 / Phase 2 switch node | Each connects to dedicated 1-µH inductor; requires low-inductance layout to minimize EMI and switching losses. |
| VO | Output voltage connection | Single output node fed by both phases; must be routed with low impedance to support 6-A ripple current. |
| FB | Feedback input | Senses output via resistive divider; internal 0.8-V reference enables precise VOUT programming from 0.9 V to 3.5 V. |
| PG | Power Good open-drain output | Signals regulation status (high = nominal VOUT); requires external pull-up for system sequencing or fault monitoring. |
| EN | Enable input | Logic-level control (0.9 V/1.0 V thresholds) with internal 350-kΩ pull-down - supports precise power sequencing. |
| SS/TR | Soft-start and tracking input | Controls startup slew rate via external capacitor; also accepts external voltage for monotonic tracking during rail ramp-up. |
| AGND / PGND | Analog / Power ground | Separate ground pins require split-plane layout: AGND for feedback/enable, PGND for high-current return paths. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-phase peak current balancing | ±10% current match at 6-A load without matched inductors or current-sense circuitry - simplifies BOM and layout. |

| Phase-shifted operation | 250 ns fixed delay between phases in PWM mode - cuts input ripple current by ~70% versus single-phase, reducing bulk capacitance requirements. |
| Integrated hiccup overcurrent protection | 0.9-ms fault detection followed by 5-ms shutdown/restart cycle - limits thermal stress during short-circuit events without latch-off. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-phase step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62180YZFR | Same pinout and package; lower max output current (4 A) and narrower VOUT range (0.9–1.8 V only). | Suitable for sub-4-A applications where 1.8-V ceiling is acceptable; lacks 2.5–3.5-V support. | Select when cost sensitivity outweighs need for 5–6 A or higher output voltages. |
| MP2964GQ-Z | 4-phase controller (external FETs); no integrated MOSFETs; requires external gate drivers and loop compensation. | Targeted at higher-current (>10 A), thermally demanding server applications with active thermal management. | Choose for scalability beyond 6 A or when discrete FET selection is required for specific RDS(ON)/Qg trade-offs. |
Compared with TPS62184YZFR, TPS62180YZFR offers identical integration and layout but reduced current/voltage capability, while MP2964GQ-Z provides higher phase count and flexibility at the cost of increased design complexity and component count.

FAQ
What is the maximum supported output voltage for TPS62184YZFR?
The TPS62184YZFR supports an output voltage range of 0.9 V to 3.5 V. This is achieved by configuring the external feedback resistor divider to set the FB pin voltage to 0.8 V. At 3.5 V output, the device delivers up to 5 A continuous current. The internal clamp limits output to approximately 7.4 V under fault conditions, protecting downstream circuitry. TPS62184YZFR maintains ±1% regulation accuracy in PWM mode across this full range.
Does TPS62184YZFR require external compensation components?
No, the TPS62184YZFR features internal compensation optimized for standard LC filter combinations - including 1-µH inductors with 2×47-µF to 8×47-µF ceramic output capacitors. This eliminates the need for external Type-II or Type-III compensation networks, reducing BOM count and layout sensitivity. TPS62184YZFR remains stable across its full operating range without user-adjustable compensation, provided recommended component values and PCB layout guidelines are followed.
How does the phase-shifted operation of TPS62184YZFR reduce EMI?
The TPS62184YZFR implements a fixed 250 ns delay between SW1 and SW2 in PWM mode, causing the two phases to switch out-of-phase. This interleaving reduces the amplitude of input current ripple by up to 70% compared to single-phase operation, directly lowering conducted EMI on the input bus. As a result, fewer or smaller input bulk capacitors are needed, and the design more easily meets CISPR-32 Class B emissions limits without additional filtering. TPS62184YZFR achieves this benefit inherently - no configuration or external timing components are required.
Can TPS62184YZFR operate with only one active phase under light load?
Yes, the TPS62184YZFR automatically transitions into Power Save Mode (PSM) at light loads, where it may activate only one phase - either master (SW1) or follower (SW2) - depending on load dynamics. This reduces switching losses and maintains high efficiency down to ~1 mA output current. In PSM, the inactive phase is fully disabled, eliminating its quiescent loss contribution. TPS62184YZFR resumes dual-phase operation seamlessly when load increases, with no user intervention or configuration needed.
What is the purpose of the SS/TR pin on TPS62184YZFR?
The SS/TR pin on TPS62184YZFR serves two functions: soft-start control and voltage tracking. When used for soft-start, an external capacitor sets the output voltage ramp rate during power-up, preventing inrush current and output overshoot. For tracking, an external voltage applied to SS/TR (50 mV to 1.2 V) causes the output to follow that reference with a gain of ~0.64 - enabling monotonic startup into pre-biased rails. TPS62184YZFR internally clamps SS/TR above 1.2 V to initiate normal regulation, and the pin tolerates up to VIN + 0.3 V.
