Product details
Overview
TPS63060MDSCTEP from Texas Instruments is a radiation-hardened, high-efficiency buck-boost DC/DC converter IC designed for dual-cell Li-ion battery-powered systems requiring regulated 2.5V–8V output. It delivers up to 2A output current in buck mode (VIN > VOUT), 1.3A in boost mode (VIN < VOUT), and features automatic mode transition, 2.4MHz fixed-frequency operation, and Power Good output. Used in defense-grade portable instrumentation and space-constrained medical telemetry devices.
For engineers reviewing the TPS63060MDSCTEP datasheet, TPS63060MDSCTEP pinout, TPS63060MDSCTEP application, or TPS63060MDSCTEP equivalent, key selection criteria include input voltage range (2.5V–12V), synchronous 4-switch topology, thermal shutdown at 140°C, 3mm × 3mm SON-10 package with exposed PowerPAD™, and military temperature rating (–55°C to 125°C).
Technical Context
The TPS63060MDSCTEP implements average current-mode control with input/output voltage feedforward for fast transient response. Its Buck-Boost Overlap Control™ prevents simultaneous conduction of opposing switches, minimizing shoot-through risk and maintaining >93% peak efficiency across buck and boost transitions.
It integrates four N-channel MOSFETs with typical RDS(on) of 90mΩ (high-side) and 95mΩ (low-side), uses separate GND (logic reference) and PGND (power ground) pins to avoid ground shift, and supports dynamic current limiting that scales ISW from ~2.0A at VIN = 12V down to ~1.3A at VIN = 2.5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5V to 12V - supports single/dual Li-ion, 3–6 alkaline/NiMH cells without external pre-regulation |
| Output Voltage Range | 2.5V to 8V - programmable via FB resistor divider or fixed internally; enables direct 3.3V/5V/8V rail generation |
| Max Output Current | 2A @ 5V (buck), 1.3A @ 5V (boost) - sufficient for FPGA I/O banks or multi-sensor modules in portable equipment |
| Switching Frequency | 2.4MHz (typical), sync-capable 2.2–2.6MHz - allows use of compact 1µH inductors and reduces EMI filtering burden |
| Quiescent Current | <30µA (typical) - extends battery life in always-on monitoring applications like implantable sensors |
| Efficiency | Up to 93% - achieved via synchronous rectification and optimized gate drive, critical for thermal-limited enclosures |
| Operating Temp | –55°C to +125°C - qualified for extended-life aerospace, downhole, and military avionics deployments |
Pinout & Package
TPS63060MDSCTEP is housed in a thermally enhanced 3mm × 3mm, 10-pin SON (DSC) package with an exposed PowerPAD™ on the bottom, requiring solder connection to PGND for optimal thermal dissipation and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| L1 | High-side switch source / inductor node | Connects to one terminal of series inductor; carries full switching current in both buck and boost phases |
| VIN | Main power input | Supplies power stage; accepts 2.5V–12V; feeds internal bias regulator for VAUX and control circuitry |
| EN | Enable control input | Active-high logic input; pulls device into ultra-low-ISHDN (≤2µA) state when low, disconnecting load from input |
| PS/SYNC | Power Save enable / clock sync input | Low = enter PFM mode at light load; high = force fixed 2.4MHz PWM; external clock accepted for EMI reduction |
| GND | Logic ground reference | Reference for EN, PS/SYNC, FB, PG; must be connected to PGND at single point near GND pin |
| VAUX | Bias capacitor terminal | Stabilizes internal LDO output; requires 0.1µF ceramic capacitor to PGND for noise immunity |
| FB | Feedback input | Senses output voltage via resistor divider; 500mV reference enables precise regulation of any VOUT ≥2.5V |
| VOUT | Regulated output | Delivers final buck-boost output; connects to bulk capacitance and system load; monitored by PG comparator |
| L2 | Low-side switch source / inductor node | Connects to second inductor terminal; complements L1 in 4-switch topology for seamless buck/boost handoff |
| PGND | Power ground return | Return path for high-current switches and inductors; must be tied to PowerPAD™ and routed separately from GND |
Key Features
| Feature | Design Value |
|---|---|
| Automatic buck-boost mode transition | Eliminates manual mode selection; maintains regulation as VIN crosses VOUT-critical for battery discharge curves |
| Load disconnect during shutdown | Prevents reverse current flow and battery drain when disabled-enables clean power sequencing in multi-rail systems |
| Power Good (PG) open-drain output | Provides early fault detection by monitoring current limit status-not just VOUT voltage-giving host MCU time to initiate safe shutdown |
| Buck-Boost Overlap Control™ | Shifts PWM ramps dynamically to suppress classical buck-boost overlap, reducing RMS switch current and improving efficiency near VIN ≈ VOUT |
| Dynamic current limit vs. VIN | Automatically scales ISW from 2.25A (VIN=12V) down to ~1.3A (VIN=2.5V), preventing overcurrent at low input while preserving headroom |
Applications
| Portable Medical Telemetry | Dual-Cell Li-ion Industrial Metering |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck-boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS63061MDSCTEP | Fixed 5V output (non-adjustable); identical package, temp range, and efficiency profile | Eliminates FB resistor network; simplifies BOM for 5V-only designs but lacks flexibility for multi-voltage systems | Select when system requires only 5V and design simplicity outweighs programmability needs |
| LM63625BQDDARQ1 | Automotive AEC-Q100 Grade 1 (–40°C to 125°C); 2.5A max output; no Power Good or VAUX pin | Qualified for automotive infotainment but lacks military temp range and PG fault signaling for safety-critical medical use | Choose for automotive platforms needing higher current; avoid where PG monitoring or extended temp range is mandatory |
Compared with TPS63060MDSCTEP, TPS63061MDSCTEP trades adjustability for reduced component count, while LM63625BQDDARQ1 offers higher current and automotive qualification but omits Power Good and military temperature support-making TPS63060MDSCTEP uniquely suited for defense and medical applications demanding both precision regulation and robust fault reporting.

FAQ
What is the maximum junction temperature specification for the TPS63060MDSCTEP?
The TPS63060MDSCTEP has an absolute maximum junction temperature of 150°C and incorporates overtemperature protection that activates at 140°C with 20°C hysteresis. This ensures reliable operation in sealed enclosures or high-ambient environments common in avionics and downhole tools, and the TPS63060MDSCTEP resumes normal function once die temperature falls below 120°C.
Does the TPS63060MDSCTEP support synchronization to an external clock?
Yes, the TPS63060MDSCTEP supports external clock synchronization via the PS/SYNC pin, accepting frequencies from 2.2MHz to 2.6MHz. The internal PLL locks to the external signal without malfunctioning during missing pulses, enabling deterministic EMI reduction in noise-sensitive systems-this capability is fully retained in the TPS63060MDSCTEP variant.
How does the TPS63060MDSCTEP handle input voltage dropout during battery discharge?
The TPS63060MDSCTEP automatically transitions between buck and boost modes as VIN crosses VOUT, maintaining regulation across the full 2.5V–12V input range. Its undervoltage lockout (UVLO) threshold of 1.8V–2.2V prevents erratic startup at end-of-discharge, and the TPS63060MDSCTEP sustains operation down to 2.5V input-critical for dual Li-ion packs discharging to 5.0V total.
What is the purpose of the VAUX pin on the TPS63060MDSCTEP?
VAUX on the TPS63060MDSCTEP supplies bias voltage to internal regulators controlling gate drivers and analog blocks. It must be decoupled with a 0.1µF ceramic capacitor to PGND to suppress noise coupling into the control loop. Unlike standard buck-boost ICs, the TPS63060MDSCTEP uses VAUX to stabilize its high-precision 500mV feedback reference-ensuring ±0.6% output accuracy across temperature.
Can the TPS63060MDSCTEP be used in a fixed-output configuration without external resistors?
No-the TPS63060MDSCTEP is the adjustable version and requires an external resistor divider on the FB pin to set VOUT. For fixed-output variants, TI offers the pin-compatible TPS63061MDSCTEP (5V) and TPS63062MDSCTEP (3.3V). The TPS63060MDSCTEP's FB pin must be connected to VOUT through R1/R2; leaving it unconnected or shorted will cause regulation failure.
