Product details
Overview
TPS62160 from Texas Instruments is an adjustable-output, 3-V to 17-V input, 1-A synchronous step-down DC/DC converter with DCS-Control™ topology, 2.25-MHz switching frequency, and integrated power good (PG) output - used in compact POL supplies for battery-powered embedded systems requiring high efficiency across light-to-heavy loads.
For engineers reviewing the TPS62160 datasheet, TPS62160 pinout, TPS62160 application, or TPS62160 equivalent, key selection considerations include its 17-µA quiescent current in power save mode, seamless PWM-to-PSM transition, 100% duty cycle capability down to VIN ≈ VOUT + 15%, and compatibility with low-ESR 22-µF output capacitors and 2.2-µH inductors.
Technical Context
The TPS62160 implements DCS-Control™ - a hybrid regulation architecture combining fast AC voltage feedback via direct comparator control with a stable DC voltage loop using internal compensation. This enables sub-10-µs transient response and <0.1%/A load regulation without external compensation components.
It integrates dual MOSFET power switches (300-mΩ high-side, 120-mΩ low-side at VIN ≥6 V), undervoltage lockout (2.7-V threshold with 180-mV hysteresis), thermal shutdown (160°C), and open-drain PG with 92–98% rising threshold - all operating within –40°C to +125°C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3 V to 17 V - supports single/dual Li-ion batteries and standard 12-V intermediate rails without external pre-regulation. |
| Output Current | Up to 1 A continuous - sufficient for core logic, FPGAs, and DSPs in space-constrained portable designs. |
| Switching Frequency | Typically 2.25 MHz - enables use of 2.2-µH inductors and reduces output ripple without sacrificing transient performance. |
| Quiescent Current | 17 µA typical in power save mode - extends battery runtime in always-on sensor nodes and IoT endpoints. |
| Output Voltage Range | Adjustable from 0.9 V to 6 V via FB pin - supports DDR termination, MCU cores, and I/O rails with single-part flexibility. |
| Power Good Output | Open-drain PG with 92–98% rising threshold - enables reliable sequencing of downstream LDOs or processors during startup. |
| Thermal Protection | 160°C shutdown with 20°C hysteresis - prevents damage during sustained overload or poor PCB thermal design. |
Pinout & Package
TPS62160 is packaged in an 8-pin WSON (DSG) package measuring 2.00 mm × 2.00 mm with exposed thermal pad - optimized for high-power-density layouts and efficient heat dissipation when soldered to AGND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PGND (Pin 1) | Power ground return | Low-impedance path for high-frequency switch node current; must be connected directly to input capacitor ground. |
| VIN (Pin 2) | Main supply input | Accepts 3–17 V; requires local 10-µF ceramic capacitor near pin for stability and EMI suppression. |
| EN (Pin 3) | Enable control input | Active-high logic; internal 400-kΩ pull-down ensures safe default-off state; supports rail sequencing. |
| AGND (Pin 4) | Analog ground reference | Reference for FB, VOS, and internal error amplifier; must be star-connected to PGND at single point. |
| FB (Pin 5) | Feedback voltage sense | Connects to resistive divider for adjustable output; tied to AGND on fixed-voltage variants to improve thermal performance. |
| VOS (Pin 6) | Output voltage sense | Direct connection to output capacitor for accurate DCS-Control™ loop response; improves line/load regulation. |
| SW (Pin 7) | Switch node | Drives external 2.2-µH inductor; requires short, low-inductance trace to minimize ringing and EMI. |
| PG (Pin 8) | Power good indicator | Open-drain output requiring external pull-up; asserts high impedance during UVLO, thermal shutdown, or EN=low. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control™ topology | Combines fast AC voltage feedback with internal DC compensation - eliminates need for external loop compensation while delivering <10-µs load transient response. |
| Seamless power save mode | Automatic, glitch-free transition between PWM and PSM - maintains >85% efficiency at 1-mA load without output voltage disturbance. |
| 100% duty cycle operation | Enables regulation down to VIN ≈ VOUT + 15% - maximizes battery runtime in Li-ion applications where input drops near output voltage. |
| Integrated protection | Includes overcurrent limiting (1.45–2.45 A), thermal shutdown (160°C), and undervoltage lockout (2.7 V with 180-mV hysteresis) - reduces system-level fault management complexity. |
| Small solution size | Supports 2.2-µH inductor and 22-µF output capacitor - achieves full 1-A design in <25 mm² PCB area including passives. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62161 | Fixed 1.8-V output; identical DCS-Control™, package, and pinout - no FB resistor network required. | Eliminates external feedback divider but lacks output adjustability; suited for dedicated 1.8-V rails only. | Select TPS62161 when 1.8 V is fixed and board space savings outweigh flexibility needs. |
| TPS62170 | Same 3–17-V input, 1-A rating, and DCS-Control™, but in 3-mm × 3-mm VSSOP (DGK); higher RθJA (184°C/W). | Compatible pinout but larger footprint and reduced thermal performance - requires more copper area for same power dissipation. | Choose TPS62170 only if VSSOP is mandated by legacy layout or assembly constraints. |
Compared with TPS62161 and TPS62170, the TPS62160 offers unique adjustability across 0.9–6 V in the smallest 2-mm × 2-mm WSON package, enabling optimal voltage scaling and minimal PCB area - critical for next-generation portable and edge AI devices.

FAQ
What is the minimum input voltage required for TPS62160 to maintain regulation at 1.8 V output?
The TPS62160 supports 100% duty cycle operation, enabling regulation when input voltage approaches the output level. For 1.8 V output, it maintains regulation down to approximately 2.07 V (15% above VOUT), as confirmed by the datasheet's 100% duty cycle specification and Equation 5 in Section 8.4.4. This allows extended runtime in single-cell Li-ion systems where VIN decays from 4.2 V to ~2.1 V.
Does TPS62160 require external compensation components?
No, the TPS62160 does not require external compensation components. Its DCS-Control™ topology uses internal compensation combined with direct AC voltage feedback, enabling stable operation with only two external components for adjustable versions: the FB voltage divider and output capacitor. This simplifies design and reduces BOM count versus traditional voltage-mode controllers.
Can TPS62160 start up into a pre-biased output?
Yes, the TPS62160 supports monotonic pre-biased startup. During this mode, the low-side MOSFET remains off until the internal ramp voltage exceeds the pre-bias level, preventing reverse current flow and ensuring controlled voltage rise. This behavior is explicitly documented in Section 8.4.1 and verified in Figure 30 of the datasheet.
What is the recommended output capacitor value for TPS62160?
The datasheet specifies 22 µF as the recommended output capacitance for the TPS62160 - validated for stability, transient response, and ripple performance across the full 0.9–6 V output range. It must be low-ESR ceramic (X5R/X7R) placed close to the SW and PGND pins. Using significantly smaller values may degrade load transient performance and increase output ripple beyond spec.
How does the power good (PG) pin behave during thermal shutdown?
During thermal shutdown, the PG pin of the TPS62160 goes into high-impedance state - identical to its behavior during EN=low or UVLO. This is confirmed in Table 1 (Power Good Pin Logic Table) in Section 8.3.3, which explicitly lists "Thermal Shutdown" under the "High Impedance" column. No external pull-up is actively driven; the signal is released to allow downstream sequencers to detect fault conditions.
