Product details

Overview

TPS57114-EP from Texas Instruments is a radiation-hardened, synchronous step-down DC/DC converter with integrated 12-mΩ high-side and low-side N-channel MOSFETs, delivering up to 3.5 A output current at 0.8 V ±1% reference accuracy over –55°C to 125°C, operating from 2.95 V to 6 V input, and supporting 200 kHz–2 MHz switching frequency via RT/CLK pin. It serves as a point-of-load regulator for FPGAs, DSPs, and ASICs in defense and aerospace systems.

For engineers reviewing the TPS57114-EP datasheet, TPS57114-EP pinout, TPS57114-EP application, or TPS57114-EP equivalent, key selection criteria include its military-grade temperature range (–55°C to 125°C), integrated boot diode, power-good comparator with 2% hysteresis, and current-mode control enabling stable operation under fast load transients in space-constrained, high-reliability power rails.

Technical Context

The TPS57114-EP implements peak-current mode control with internal slope compensation to prevent subharmonic oscillation above 50% duty cycle, using a transconductance error amplifier (245 µS) referenced to a 0.8-V ±1% bandgap voltage. Its PLL-synchronized RT/CLK interface allows external clock alignment down to 300 kHz.

Protection features include thermal shutdown (168°C), frequency foldback during overcurrent, BOOT-PH UVLO (2.1 V), and programmable EN-pin UVLO via resistor divider. The device supports 100% duty-cycle operation when BOOT-PH > 2.2 V and provides slow-start/tracking via SS/TR pin with 2 µA charge current.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Voltage Range	2.95 V to 6 V - Enables direct regulation from common intermediate bus rails including 3.3 V and 5 V supplies.
Output Current	3.5 A continuous - Sufficient for powering core logic of mid-tier FPGAs and microprocessors without external current boosting.
Reference Accuracy	0.8 V ±1% over –55°C to 125°C - Ensures tight output regulation across full military temperature range without calibration.
Switching Frequency	200 kHz to 2 MHz - Adjustable via RT resistor or external clock; higher frequencies allow smaller inductors and output capacitors.
Quiescent Current	515 µA typical - Minimizes no-load power loss in always-on subsystems such as telemetry or watchdog circuits.
Shutdown Current	5.5 µA max - Supports ultra-low-power standby modes in battery-backed or energy-harvested space payloads.
MOSFET R_DS(on)	12 mΩ high-side / 13 mΩ low-side @ 5 V - Delivers >90% efficiency at 3.5 A, 1.8 V out, reducing thermal load in sealed enclosures.

Pinout & Package

TPS57114-EP is housed in a thermally enhanced 3-mm × 3-mm, 16-pin WQFN package with exposed thermal pad (PowerPAD™) for low-junction-to-board thermal resistance (R_θJB = 16°C/W).

Pin/Terminal	Circuit Role	Design Meaning
VIN	Input supply connection	Accepts 2.95–6 V; must be decoupled locally with ≥10 µF ceramic capacitor to suppress high-frequency ripple.
PH	Power stage switch node	Connects to inductor; carries high dv/dt switching waveform-requires tight layout to minimize EMI and shoot-through risk.
BOOT	High-side gate drive supply	Requires 0.1 µF X7R/X5R ceramic capacitor to PH; UVLO disables high-side if BOOT–PH < 2.1 V.
VSENSE	Feedback input	Inverting input of transconductance error amplifier; sets output voltage via resistor divider to 0.8 V reference.
COMP	Error amplifier output	Drives current-mode comparator; connects to RC compensation network for loop stability.
EN	Enable / UVLO control	Pulled up internally; disable below 1.18 V; threshold adjustable with resistor divider for custom input-voltage turn-on.
RT/CLK	Frequency setting	Resistor-to-ground sets frequency (200–2000 kHz); accepts external clock (300–2000 kHz) with PLL lock in 42 µs.
SS/TR	Soft-start / tracking	2 µA current source charges external capacitor; enables controlled ramp-up or voltage sequencing with other rails.
PWRGD	Power-good indicator	Open-drain output asserts low when V_OUT falls outside 93–107% of nominal; 2% hysteresis prevents chatter.
AGND	Analog ground reference	Must be connected to GND near device; separates noise-sensitive analog circuitry from power ground paths.
GND	Power ground	Electrically tied to exposed thermal pad; requires multiple vias to inner ground plane for thermal and EMI performance.

Key Features

Feature	Design Value
Integrated MOSFETs	12-mΩ high-side + 13-mΩ low-side enable compact, high-efficiency 3.5-A buck design without external switches.
Current-mode control	Enables fast transient response and inherent pulse-by-pulse current limiting-critical for FPGA core rail stability.
Boot diode integration	Eliminates external bootstrap diode, simplifying layout and improving reliability in high-vibration aerospace environments.
Extended temperature support	Specified for –55°C to 125°C operation with controlled baseline, extended lifecycle, and traceability per MIL-PRF-38535.
Power-good with hysteresis	93–107% window and 2% hysteresis ensure deterministic system reset and sequencing in radiation-prone deployments.

Equivalent & Alternatives

The following parts are listed as comparable options for similar synchronous buck converter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS54318-EP	Lower 3-A output rating; fixed 500-kHz frequency; no RT/CLK synchronization; 0.8-V reference same tolerance.	Lacks programmable soft-start and external clock sync-less suitable for multi-rail sequencing or EMI-sensitive radar systems.	Select when cost sensitivity outweighs flexibility needs and 3-A output suffices for lower-power ASICs.
LM61480-Q1	Automotive AEC-Q100 qualified; 8-A rating; 2.5-V to 36-V input; no extended temperature grade; different pinout and compensation scheme.	Not radiation-hardened or MIL-qualified; unsuitable for space or defense use; broader input range targets vehicle battery systems.	Choose only for non-military automotive designs requiring higher current and wider VIN range.

Compared with TPS57114-EP, TPS54318-EP offers reduced feature set but lower BOM count, while LM61480-Q1 trades radiation tolerance and military qualification for automotive robustness and higher current-neither is pin-compatible, and both require PCB redesign and loop compensation revalidation.

FAQ

What is the maximum output current supported by the TPS57114-EP?

The TPS57114-EP delivers up to 3.5 A continuous output current under recommended operating conditions (T_J ≤ 125°C, proper thermal layout). Its integrated 12-mΩ high-side and 13-mΩ low-side MOSFETs enable this rating without external switches. Derating is required above 125°C junction temperature, and actual achievable current depends on ambient temperature, PCB copper area, and airflow-TI's derating chart shows ~2.8 A at 125°C ambient with standard JEDEC board.

Does the TPS57114-EP support external clock synchronization?

Yes, the TPS57114-EP supports external clock synchronization via its RT/CLK pin. When driven by an external clock signal (300 kHz–2 MHz), the internal PLL locks within 42 µs and aligns the high-side switch turn-on edge to the falling edge of the input clock. This capability reduces beat frequencies and EMI in multi-converter systems such as phased-array radar or multi-core processors where timing coherence is essential.

How is the output voltage set on the TPS57114-EP?

The output voltage of the TPS57114-EP is set using a resistor divider from V_OUT to the VSENSE pin, referenced to the internal 0.8-V ±1% voltage reference. For example, a 100-kΩ top resistor (R1) and 100-kΩ bottom resistor (R2) yields 1.6 V output. TI recommends 1% tolerance resistors and cautions against excessively large values (>1 MΩ) due to VSENSE input current-induced errors and noise susceptibility.

What protection features does the TPS57114-EP include?

The TPS57114-EP integrates thermal shutdown (168°C with 20°C hysteresis), overcurrent protection via peak-current limiting, BOOT-PH UVLO (2.1 V), input UVLO (2.45 V start), output overvoltage detection (109% trip), undervoltage detection (91% trip), and frequency foldback during fault conditions. These protections operate autonomously without external components, ensuring safe recovery and preventing damage during abnormal operating conditions in mission-critical systems.

Is the TPS57114-EP compatible with standard WQFN reflow profiles?

Yes, the TPS57114-EP uses a standard 3-mm × 3-mm WQFN package qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 3 and compatible with industry-standard lead-free reflow profiles (peak temperature ≤ 260°C). Its exposed thermal pad requires solder paste stencil design with ≥70% open area and at least six 0.3-mm vias to inner ground planes to ensure mechanical integrity and thermal performance per TI's layout guidelines.
