Product details
Overview
TPS63060-EP from Texas Instruments is a radiation-hardened, high-efficiency buck-boost DC/DC converter IC designed for wide-input military and aerospace power systems. It delivers up to 2A output current in buck mode (VIN > VOUT) and 1.3A in boost mode (VIN < VOUT), operates across 2.5V–12V input, supports fixed or adjustable 2.5V–8V output, and features Power Good signaling, overtemperature/overvoltage protection, and 2.4MHz forced-frequency operation - enabling reliable power conversion in dual-cell Li-ion battery-powered avionics and space-grade telemetry units.
For engineers reviewing the V62/14602-01XE datasheet, V62/14602-01XE pinout, V62/14602-01XE application, or V62/14602-01XE equivalent, this page provides verified electrical specifications, thermal metrics, military-grade operating conditions (–55°C to 125°C), SON-10 package layout, and design-critical functional behavior including Buck-Boost Overlap Control™, dynamic current limiting, and Power Save Mode transition thresholds.
Technical Context
The TPS63060-EP implements an average-current-mode, 4-switch synchronous buck-boost topology with input/output voltage feedforward for fast transient response. Its control loop uses a transconductance amplifier and dual ramp modulation to avoid subharmonic oscillation without slope compensation, while Buck-Boost Overlap Control™ eliminates classical buck-boost switching cycles that degrade efficiency near VIN ≈ VOUT.
It integrates dual N-channel MOSFETs per switch leg (high-side/low-side), separate GND and PGND pins to isolate logic and power return paths, and a temperature-sensing circuit triggering shutdown at 140°C with 20°C hysteresis. The PS/SYNC pin enables Power Save Mode (PFM) below ~100mA average inductor current or external clock synchronization between 2.2–2.6MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5V to 12V - supports three-to-six-cell alkaline/NiMH and one-to-two-cell Li-ion battery inputs without external regulators. |
| Output Voltage Range | 2.5V to 8V - programmable via external resistor divider or internally fixed; feedback reference is 500mV ±1%. |
| Switch Current Limit | 2.25A typical - sets maximum sustainable output current in buck mode (e.g., 2A @ 5V with VIN ≥10V) and limits peak stress during load transients. |
| Efficiency | Up to 93% - achieved using synchronous rectification and optimized gate drive; maintains >85% efficiency from 10mA to full load at VOUT=5V. |
| Quiescent Current | <30μA - enables multi-year battery life in always-on sensor nodes and low-duty-cycle telemetry systems. |
| Operating Temperature | –55°C to +125°C - qualified for extended-life deployment in satellite power subsystems and downhole industrial metering. |
| Switching Frequency | 2.4MHz nominal - allows use of compact 1μH inductors and minimizes EMI filtering requirements in size-constrained PCB layouts. |
Pinout & Package
Package: 3-mm × 3-mm, 10-pin SON (DSC) with exposed PowerPAD™ thermal pad - requires soldering to PGND plane for thermal performance (θJCbot = 4.2°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| L1 | Power input to high-side buck switch / low-side boost switch | Connects to first external inductor; carries full switching current in both buck and boost phases. |
| VIN | Main power input supply | Supplies bias and power stage; must be decoupled with ≥2×10μF ceramic capacitors close to pin. |
| EN | Digital enable control | Active-high logic input; pulls device into ultra-low-ISHDN (≤2μA) state when grounded, disconnecting load from input. |
| PS/SYNC | Mode selection and clock sync | Low = Power Save Mode (PFM); high = forced PWM; external clock input enables system-level timing alignment. |
| GND | Analog/logic reference ground | Reference for FB, EN, PS/SYNC, and internal control circuits - must tie to PGND at single point near GND pin. |
| FB | Output voltage feedback | Connects to resistor divider for adjustable versions; tied directly to VOUT for fixed-output variants. |
| VOUT | Regulated power output | Delivers stable output; requires ≥3×22μF ceramic capacitance for transient response and ripple suppression. |
| VAUX | Bias capacitor connection | Stabilizes internal bias regulator; requires 10pF ceramic capacitor to PGND for noise immunity. |
| PG | Open-drain Power Good indicator | Asserts low when VOUT is within ±3.5% of regulation; enables safe system boot sequencing and fault detection. |
| L2 | Power input to low-side buck switch / high-side boost switch | Connects to second external inductor; complements L1 to complete 4-switch buck-boost power path. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic buck/boost mode transition | Seamlessly shifts topology based on VIN vs. VOUT ratio - no external control needed and no output interruption during crossover. |
| Buck-Boost Overlap Control™ | Prevents simultaneous conduction of opposing switches - reduces RMS current, conduction loss, and EMI at mid-range input voltages. |
| Dynamic current limiting | Reduces ISW limit as VIN decreases or junction temperature rises - protects against thermal runaway under weak input sources. |
| Load disconnect during shutdown | Opens internal FETs to isolate VOUT from VIN - prevents backfeed, enables true zero-load battery drain, and supports hot-swap capability. |
| Power Good with early-fault detection | Monitors current control loop status - asserts PG low before VOUT deviation exceeds specification, allowing time-critical system response. |

FAQ
What is the absolute maximum input voltage rating for V62/14602-01XE?
The absolute maximum input voltage for V62/14602-1XE is 17V applied to VIN, L1, L2, PS/SYNC, EN, and FB pins. Exceeding this value may cause permanent damage. The recommended operating range remains 2.5V to 12V per the datasheet's Recommended Operating Conditions table, and operation above 12V voids guaranteed performance and reliability specifications.
Does V62/14602-01XE support fixed-output voltage configurations?
Yes, V62/14602-01XE supports both fixed and adjustable output voltage configurations. Fixed-output versions use an internally trimmed resistor divider referenced to the 500mV feedback threshold; for those variants, the FB pin must be connected directly to VOUT. Adjustable versions require an external resistor divider from VOUT to GND with the midpoint connected to FB.
How does the Power Good (PG) output function in V62/14602-01XE?
The PG output in V62/14602-01XE is an open-drain signal that goes low-impedance when VOUT deviates more than ±3.5% from its nominal value. It monitors the current control loop in real time - asserting fault before significant VOUT droop occurs - and requires an external pull-up resistor to the host logic rail. This enables precise power sequencing and early fault detection in safety-critical systems.
Can V62/14602-01XE operate with only one external inductor?
No, V62/14602-01XE requires two external inductors - one connected to L1 and one to L2 - as specified in the Pin Functions table and Functional Block Diagram. The 4-switch buck-boost architecture relies on independent magnetic energy storage in each inductor to achieve seamless mode transitions and minimize ripple. Using a single inductor violates the topology and will result in failure to regulate.
What thermal metrics define the cooling performance of V62/14602-01XE?
V62/14602-01XE is characterized with θJCbot = 4.2°C/W (junction-to-case bottom), θJB = 19.8°C/W (junction-to-board), and ψJB = 19.6°C/W (junction-to-board characterization parameter). These values assume proper soldering of the PowerPAD™ to a dedicated PGND copper area - achieving ≤125°C junction temperature requires ≥4 cm² of 2-oz copper connected to the exposed pad under standard JEDEC high-K board conditions.
