Product details
Overview
TPS62180YZFT from Texas Instruments is an adjustable-output, dual-phase synchronous step-down DC-DC converter optimized for low-profile power delivery in space-constrained systems. It delivers up to 6 A continuous output current across two balanced 3-A phases, operates from 4 V to 15 V input, regulates output voltage from 0.9 V to 6 V with ±1% accuracy in PWM mode, and features Automatic Efficiency Enhancement (AEE™) for high efficiency across wide duty cycles - used in ultra-portable computing and NVDC battery-powered systems.
For engineers reviewing the TPS62180YZFT datasheet, TPS62180YZFT pinout, TPS62180YZFT application, or TPS62180YZFT equivalent, key selection considerations include its 24-bump DSBGA package (2.10 mm × 3.10 mm), phase-shifted 250 ns delay in PWM mode, 28 µA quiescent current, integrated HICCUP overcurrent protection, and adjustable soft-start via external capacitor on SS/TR pin.
Technical Context
The TPS62180YZFT implements a predictive OFF-time peak current control topology with dual independent current loops - master (Phase 1) and follower (Phase 2) - sharing identical regulation thresholds and cycle-by-cycle peak current setpoints. This ensures precise phase current balancing (±10% at 6 A) without requiring matched inductors or PCB routing.
It supports three functional modes: fixed-frequency PWM for heavy loads, discontinuous conduction mode (DCM) Power Save Mode (PSM) for light loads with reduced switching frequency, and 100% duty cycle operation when VIN approaches VOUT - enabled by unclamped high-side FET control and AEE™-adjusted off-time to maintain efficiency down to 0.9 V output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4 V to 15 V - supports multi-cell Li-ion batteries and standard 12-V rails without external pre-regulation. |
| Output Voltage Range | 0.9 V to 6 V (adjustable) - set via external resistor divider on FB pin; enables single IC for multiple rail requirements. |
| Max Output Current | 6 A continuous - delivered by two 3-A phases operating out-of-phase, reducing input RMS current and EMI. |
| Quiescent Current | 28 µA typical - enables >100-hour battery runtime in always-on subsystems without compromising light-load efficiency. |
| Output Accuracy | ±1% in PWM mode - ensures stable core voltage for processors/FPGAs under dynamic load transients. |
| Switching Frequency | Auto-adjusted via AEE™ - maintains optimal efficiency across VIN/VOUT combinations without external compensation. |
| Thermal Shutdown | 160°C with 20°C hysteresis - protects against sustained overload or poor PCB thermal design while enabling automatic recovery. |
Pinout & Package
TPS62180YZFT is housed in a 24-bump, 0.5-mm pitch NanoFree™ DSBGA package measuring 2.10 mm × 3.10 mm - optimized for ultra-thin portable designs with minimal board area and height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW1, SW2 | Phase 1 and Phase 2 switch nodes | Connect to respective 1-µH inductors; each drives 3-A phase current with internal 27-mΩ (HS1) and 21-mΩ (LS1) MOSFETs. |
| VIN1, VIN2 | Independent phase input supplies | Enable separate decoupling per phase; reduces input ripple and improves transient response vs. shared VIN. |
| VO | Main output voltage connection | Single-point output node for 6-A combined current; requires ≥2×47 µF ceramic output capacitance for stability. |
| FB | Feedback voltage sensing input | Monitors output via external resistor divider; internal 0.8-V reference enables precise VOUT programming (e.g., 1.2 V, 1.8 V, 3.3 V). |
| EN | Enable control with accurate threshold | Starts/stops conversion with ±3% threshold (0.9–1.03 V); internal 350-kΩ pull-down prevents floating during sequencing. |
| SS/TR | Soft-start and tracking control | External capacitor sets startup slew rate; also accepts 50 mV–1.2 V tracking voltage to coordinate with other rails. |
| PG | Open-drain power-good indicator | Signals VOUT regulation status (94–98% nominal); requires external pull-up; asserts low during UVLO, thermal shutdown, or disable. |
| AGND / PGND | Analog and power ground terminals | Separate AGND (C4) and multi-pin PGND (A3–F3) minimize noise coupling between control and power paths. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-phase current balancing | ±10% phase current mismatch at full 6-A load - eliminates need for matched inductors or current-sense calibration. |
| Automatic Efficiency Enhancement (AEE™) | Dynamic OFF-time adjustment maintains >90% efficiency across 4–15 V input and 0.9–6 V output - avoids efficiency cliffs in fixed-frequency converters. |
| Phase-shifted operation | 250 ns fixed delay between SW1 and SW2 in PWM mode - cuts input capacitor RMS current by ~30% and lowers EMI peaks. |
| Power Save Mode (PSM) | Reduces switching frequency linearly with load - sustains >85% efficiency at 10-mA load with 28-µA IQ. |
| HICCUP overcurrent protection | 0.9-ms fault detection + 5-ms restart cycle - limits average power during short-circuit while preventing thermal runaway. |
| 100% duty cycle capability | No minimum ON-time limitation - supports VIN as low as VOUT + (IL × RDS(ON)) for extended battery discharge life. |

FAQ
What is the recommended output capacitor configuration for stable operation of the TPS62180YZFT?
The TPS62180YZFT requires a minimum of two 47-µF ceramic capacitors (X5R/X7R, 6.3-V rating) placed close to the VO and PGND pins. This configuration ensures sufficient bulk capacitance to suppress output ripple below 20 mVpp under 6-A load steps, maintains loop stability across temperature, and supports the device's 250 ns phase-shifted switching to minimize input current harmonics. Using fewer or lower-value capacitors risks instability and excessive voltage deviation during transients.
How does the TPS62180YZFT achieve current balancing between its two phases without current-sense circuitry?
The TPS62180YZFT achieves phase current balancing through identical peak current control loops - each phase uses the same internal reference and cycle-by-cycle current limit threshold, enforced by matched high-side and low-side MOSFET RDS(ON) values. Because both loops regulate to the same output voltage and share identical timing (with fixed 250 ns phase delay), they inherently draw equal average current without needing external current sensing or trimming - verified to ±10% at 6 A across temperature and line variations.
Can the TPS62180YZFT operate with only one active phase under light load conditions?
Yes, the TPS62180YZFT automatically enters Power Save Mode (PSM) at light loads, where it may deactivate one phase entirely - allowing the remaining phase to deliver the full load current while maintaining high efficiency. This behavior is transparent to the user and occurs without external control; the device resumes dual-phase operation seamlessly when load increases beyond the PSM exit threshold, ensuring optimal efficiency across the entire 1-mA to 6-A load range.
What is the function of the SS/TR pin on the TPS62180YZFT, and how is it used for tracking?
The SS/TR pin on the TPS62180YZFT serves dual functions: soft-start control (via external capacitor) and voltage tracking. For tracking, an external voltage source (50 mV to 1.2 V) applied to SS/TR causes the FB pin to follow it at ~0.64× gain - enabling coordinated ramp-up with other rails. When SS/TR reaches ~1.2 V, the internal reference clamps and normal regulation begins. This allows safe power sequencing in multi-rail systems without additional controllers.
Does the TPS62180YZFT support 100% duty cycle operation, and what is its practical benefit?
Yes, the TPS62180YZFT supports true 100% duty cycle operation - turning on both high-side FETs continuously when VIN approaches VOUT - with no minimum ON-time limitation. This extends usable input voltage range down to VOUT + (ILOAD × RDS(ON)), enabling longer battery runtime in Li-ion systems (e.g., sustaining 3.3-V output until battery drops to ~3.6 V), and eliminating dropout-related system resets during deep discharge.
