Product details
Overview
TPS62000SKGD1 from Texas Instruments is a high-efficiency synchronous step-down DC-DC converter optimized for extreme-temperature down-hole drilling and high-reliability industrial environments. It operates from 2 V to 5.5 V input, delivers up to 300 mA output current, supports adjustable output voltage (0.8 V to VI), and achieves >95% efficiency at full load with 50 µA typical quiescent current in power-save mode.
For engineers reviewing the TPS62000SKGD1 datasheet, TPS62000SKGD1 pinout, TPS62000SKGD1 application, or TPS62000SKGD1 equivalent, key selection considerations include its –55°C to 210°C operating range, pin-programmable current limit (600 mA or 1.2 A), 750 kHz nominal switching frequency, PFM/PWM mode control via SYNC pin, and HKK bare-die package compatibility with high-temperature packaging solutions.
Technical Context
The TPS62000SKGD1 implements a current-mode synchronous PWM architecture with integrated N- and P-channel MOSFETs, enabling 100% duty-cycle operation for ultra-low dropout. Its internal compensation eliminates external compensation components, while the antiringing switch (disabled in adjustable versions) and soft-start circuit reduce EMI and inrush current.
Operation dynamically shifts between fixed-frequency PWM (750 kHz, forced by SYNC = HIGH) and pulse-frequency modulation (PFM) at light loads to maintain >90% efficiency from 10 mA to 300 mA. The device features undervoltage lockout (1.6 V threshold), shutdown current <1 µA, and synchronization capability across 500–1000 kHz external clock signals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2 V to 5.5 V - supports single-cell Li-ion and 2–3-cell alkaline/NiMH/NiCd battery systems without external LDO pre-regulation. |
| Output Current | Up to 300 mA - sufficient for powering microcontrollers, sensors, and RF transceivers in high-temp embedded systems. |
| Output Voltage Range | 0.8 V to VI - fully adjustable via external resistor divider; enables precise rail generation for low-voltage logic and analog circuits. |
| Quiescent Current | 50 µA (typ) in PFM mode - extends battery life in intermittently active monitoring systems deployed in remote down-hole locations. |
| Switching Frequency | 750 kHz (typ), synchronizable 500–1000 kHz - allows use of compact 10 µH inductors and minimizes EMI filtering component count. |
| Operating Temperature | –55°C to 210°C - qualified for down-hole drilling electronics, aerospace actuators, and geothermal sensor nodes where standard ICs fail. |
| Efficiency | >95% at 300 mA - reduces thermal stress in sealed, convection-limited enclosures common in oilfield tools. |
Pinout & Package
TPS62000SKGD1 is supplied as a bare die in the HKK package format (10-pin, top-side bond pads), intended for integration into custom high-temperature modules or ceramic substrates. Die dimensions are 1524 µm × 2184 µm with 15-mil thickness and Al-Si-Cu metallization.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FB | Feedback Input | Connects to external resistor divider to set output voltage; disables internal reference divider for full adjustment flexibility. |
| SYNC | Mode Control Input | Logic HIGH forces fixed-frequency PWM; LOW enables automatic PFM/PWM transition for optimal light-load efficiency. |
| EN | Enable Input | Active-HIGH enable with <1 µA shutdown current; supports system-level power sequencing and wake-up control. |
| L | Switch Node | Drain connection of internal P- and N-channel MOSFETs; requires low-inductance routing to external 10 µH inductor. |
| PGND | Power Ground | Separate return path for high-current switching loop; must be isolated from signal GND to minimize noise coupling. |
| VIN | Input Supply | Primary power input; requires 10 µF low-ESR ceramic capacitor placed adjacent to pin for stable high-frequency decoupling. |
| FC | Filter Capacitor | Bypass pin for high-frequency input noise suppression; 0.1 µF capacitor required close to die for optimal regulation stability. |
| GND | Signal Ground | Analog reference ground for error amplifier and internal bias circuits; must be connected to PGND at single point near die. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous Rectification | Integrated N- and P-channel MOSFETs eliminate external diode, reducing conduction loss and enabling >95% peak efficiency. |
| 100% Duty Cycle Operation | Enables dropout voltage as low as RDS(on) × IOUT; maintains regulation even when input drops within ~100 mV of output voltage. |
| Programmable Current Limit | Two settings: 600 mA (ILIM to GND) or 1.2 A (ILIM to VIN); protects against short-circuit faults without requiring external sense resistors. |
| Internal Soft-Start | 1 ms typical ramp time prevents output overshoot and limits inrush current during cold start in high-capacitance systems. |
| Undervoltage Lockout | 1.6 V threshold prevents erratic startup or brownout operation when battery voltage falls below safe regulation margin. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62000SHKK | Same die, packaged in 10-pin HKK laminate; includes bond wire interconnects and molded encapsulation. | Requires standard PCB assembly vs. die bonding; suitable for prototyping or lower-volume production where bare-die integration is impractical. | Select TPS62000SHKK when using conventional SMT processes or evaluating functionality before committing to custom module design. |
| LM70880QPWPRQ1 | Automotive-grade 3-A buck with -40°C to 150°C rating; higher current, wider input range (2.7–18 V), but no 210°C qualification. | Targeted at automotive engine bay applications; lacks extreme-temperature validation and has larger footprint. | Choose LM70880QPWPRQ1 only if ambient temperature remains ≤150°C and higher output current or input voltage range is required. |
Compared with TPS62000SHKK, the TPS62000SKGD1 offers direct die attach for superior thermal resistance in hermetic modules, while LM70880QPWPRQ1 provides higher current and automotive qualification but cannot operate above 150°C - making TPS62000SKGD1 the sole option for verified 210°C continuous operation.

FAQ
What is the maximum ambient temperature rating for the TPS62000SKGD1?
The TPS62000SKGD1 is characterized and specified for continuous operation from –55°C to 210°C ambient temperature. This rating is validated per TI's controlled baseline process and extended product lifecycle program, making it suitable for down-hole drilling tools and geothermal instrumentation where standard converters fail.
Does the TPS62000SKGD1 support adjustable output voltage?
Yes, the TPS62000SKGD1 is the adjustable-output version of the TPS62000-HT family. It uses the FB pin to connect an external resistor divider, enabling output voltages from 0.8 V up to the input voltage (VI). The internal feedback divider is disabled, allowing full design flexibility for custom rail generation.
How does the SYNC pin affect operation of the TPS62000SKGD1?
The SYNC pin on the TPS62000SKGD1 controls the operating mode: logic HIGH forces fixed-frequency PWM operation (reducing EMI), while logic LOW enables automatic PFM/PWM transition for highest light-load efficiency. It also accepts external clock signals from 500 kHz to 1000 kHz for system-level timing synchronization.
What package type is used for the TPS62000SKGD1?
The TPS62000SKGD1 is supplied as a bare die in the HKK format - a 10-pad, silicon-die-only configuration measuring 1524 µm × 2184 µm. It is intended for integration into custom high-temperature modules, ceramic substrates, or hybrid packages, not for standard PCB mounting.
Can the TPS62000SKGD1 be used with input voltages below 2 V?
No - the absolute minimum input voltage for the TPS62000SKGD1 is 2 V per datasheet specifications. Although the device may function briefly at 1.8 V under certain conditions, undervoltage lockout activates below 1.6 V, and guaranteed operation (including regulation, efficiency, and current limit) begins only at 2 V.
