Product details
Overview
TPS62184YZFT 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, operating from 4 V to 17 V input and supporting 0.9 V–3.5 V programmable output voltage with ±1% accuracy in PWM mode. It integrates peak current-mode control, Automatic Efficiency Enhancement (AEE™), and phase-shifted operation for low-noise, height-constrained POL supplies in battery-powered computing systems.
For engineers reviewing the TPS62184YZFT datasheet, TPS62184YZFT pinout, TPS62184YZFT application, or TPS62184YZFT equivalent, key selection considerations include its 24-bump DSBGA package (2.10 mm × 3.10 mm), 250 ns inter-phase delay in PWM mode, 28 µA quiescent current, dual VIN inputs (VIN1/VIN2), and integrated HICCUP overcurrent protection with thermal shutdown at 160°C.
Technical Context
The TPS62184YZFT implements a predictive OFF-time peak current control topology with separate master/follower current loops sharing identical peak current setpoints and regulation thresholds-enabling precise per-phase current balancing within ±10% at full 6-A load without requiring matched inductors. Its AEE™ algorithm dynamically adjusts switching frequency based on VIN and VOUT to maintain high efficiency across wide duty cycles, especially critical for low-VOUT/high-VIN conversion.
Phase-shifted operation reduces input RMS current and EMI: phases operate with fixed 250 ns delay in PWM mode and ~100 ns in Power Save Mode. The device supports monolithic 100% duty cycle operation down to minimal VIN–VOUT differential and includes internal compensation, soft-start via external SS/TR capacitor, and open-drain PG with 90–98% VOUT threshold hysteresis.
Key Specifications

Pinout & Package
TPS62184YZFT is housed in a 24-bump, 0.5 mm pitch DSBGA (YZF) package measuring 2.10 mm × 3.10 mm, optimized for low-height applications with direct die attach and minimal thermal path resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW1, SW2 | Phase 1 and Phase 2 switch nodes | Connect to respective 1-µH inductors; each drives half the 6-A load with synchronized but phase-delayed switching to reduce input ripple. |
| VIN1, VIN2 | Independent phase supply inputs | Enable distributed power routing; decoupling capacitors placed locally per phase improve transient response and reduce ground bounce. |
| VO | Main output voltage connection | Single-point connection for output capacitors (e.g., 4×47 µF); ties both phases' outputs together for unified 6-A delivery. |
| FB | Feedback reference input | Regulates output to 0.8 V internal reference; resistor divider sets VOUT from 0.9 V to 3.5 V with ±1% accuracy in PWM mode. |
| PG | Power Good open-drain output | Signals VOUT stability (94% nominal rise / 92% fall threshold); requires external pull-up; sinks 2 mA for system sequencing and fault indication. |
| EN | Enable control input | Active-high with 0.9–1.03 V threshold; internal 350-kΩ pull-down ensures safe default-off state; initiates soft start after 100 µs delay. |
| SS/TR | Soft-start and tracking input | External capacitor sets output ramp rate; also accepts external voltage (50 mV–1.2 V) for monotonic startup into pre-biased rails. |
| AGND, PGND | Analog and power ground | Separate AGND (C4) and PGND (A3–F3) pins require dedicated PCB copper pours tied at single point to minimize noise coupling into feedback path. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-phase current balancing | ±10% matching at 6-A load without matched inductors-achieved via cycle-by-cycle peak current control and fixed-phase delay. |
| Automatic Efficiency Enhancement (AEE™) | Dynamically adjusts switching frequency across VIN/VOUT range to maintain >90% efficiency at light and heavy loads, eliminating efficiency cliffs in low-duty-cycle operation. |
| Phase-shifted PWM operation | 250 ns inter-phase delay reduces input RMS current by ~70%, allowing smaller input capacitors and easing EMI compliance in space-constrained designs. |
| Integrated 100% duty cycle mode | Enables operation down to VIN–VOUT < 100 mV-critical for maximizing runtime in fading multi-cell Li-ion battery applications without dropout. |
| Monotonic pre-biased startup | SS/TR pin supports tracking mode (50 mV–1.2 V input) to safely ramp output from existing voltage levels-prevents reverse current and system reset during hot-plug events. |

FAQ
What is the maximum continuous output current supported by the TPS62184YZFT?
The TPS62184YZFT delivers up to 6 A continuous output current, split equally across two balanced 3-A phases. This rating holds across the full output voltage range: 0.9–1.8 V (6 A), 1.8–2.5 V (5.5 A), and 2.5–3.5 V (5 A), as specified in the datasheet's Recommended Operating Conditions table. The dual-phase architecture enables this high current with low-profile external components.
Does the TPS62184YZFT support operation with a pre-biased output voltage?
Yes, the TPS62184YZFT supports monotonic startup into a pre-biased output via its SS/TR pin in tracking mode. When an external voltage between 50 mV and 1.2 V is applied to SS/TR, the FB pin tracks it with ~0.64× gain, allowing controlled ramp-up from an existing rail. The device does not sink current from the output during tracking, ensuring safe hot-plug behavior without causing voltage droop or system reset.
What is the purpose of the dual VIN inputs (VIN1 and VIN2) on the TPS62184YZFT?
VIN1 and VIN2 provide independent power inputs for each of the two phases, enabling flexible PCB layout with localized decoupling. This separation reduces shared impedance, improves transient response, and minimizes ground bounce between phases. It also allows asymmetric input routing-for example, connecting VIN1 to a primary 12-V rail and VIN2 to a backup battery source-without requiring external OR-ing circuitry.
How does the Automatic Efficiency Enhancement (AEE™) feature improve performance in the TPS62184YZFT?
AEE™ in the TPS62184YZFT dynamically adjusts the switching frequency based on real-time VIN and VOUT to maintain high efficiency across all duty cycles. Unlike fixed-frequency converters that suffer efficiency drops at low VOUT or high VIN, AEE™ preserves >90% efficiency from 0.9 V to 3.5 V outputs and 4 V to 17 V inputs by optimizing off-time-reducing switching losses while keeping inductor ripple current within safe limits.
What thermal protection mechanisms are built into the TPS62184YZFT?
The TPS62184YZFT incorporates thermal shutdown triggered at 160°C junction temperature (typical), with 20°C hysteresis. Upon activation, both high-side FETs turn off, the output discharge resistor (60 Ω) engages, and the PG pin goes low-signaling fault condition. Once junction temperature falls below 140°C, the device automatically resumes operation with a full soft-start sequence, ensuring reliable recovery without manual intervention.
