Product details
Overview
TPS62510DRCTG4 from Texas Instruments is a synchronous step-down DC-DC converter optimized for 1.8-V to 3.8-V input rails, delivering up to 1.5 A at adjustable output voltages down to 0.6 V. It features 1.5-MHz fixed-frequency PWM operation, power-save mode for light-load efficiency, 22-μA quiescent current, and output voltage tracking (OVT) for controlled power sequencing in portable systems.
For engineers reviewing the TPS62510DRCTG4 datasheet, TPS62510DRCTG4 pinout, TPS62510DRCTG4 application, or TPS62510DRCTG4 equivalent, key selection criteria include input voltage range compatibility with 2-cell alkaline/NiMH batteries, OVT-enabled core/I/O rail coordination, thermal shutdown at 160°C, and VSON-10 package suitability for space-constrained mobile designs.
Technical Context
The TPS62510DRCTG4 employs voltage-mode control with input-voltage feed-forward for fast line/load regulation and supports both forced PWM (MODE = high) and automatic PFM/PWM transition (MODE = low). Its dual MOSFET power stage integrates a P-channel high-side switch (120 mΩ typical RDS(on) at 3.3 V) and N-channel low-side rectifier (80 mΩ typical), enabling 96% peak efficiency and 100% duty-cycle low-dropout operation.
Functional modes are managed via dedicated pins: OVT enables external reference tracking below 0.6 V; EN provides logic-level enable/disable; PG delivers open-drain power-good indication with ±5% threshold hysteresis; AVIN and PVIN separate analog and power supply domains to minimize noise coupling into control circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 1.8 V to 3.8 V - supports direct operation from 2-cell alkaline/NiMH or fixed 3.3/2.5/1.8-V rails without pre-regulation. |
| Output Current | 1.5 A continuous - sufficient for powering processor cores, FPGAs, or RF transceivers in portable devices. |
| Switching Frequency | 1.5 MHz (fixed PWM) - enables use of small 2.2-μH inductors and 22-μF ceramic output capacitors for compact PCB layout. |
| Quiescent Current | 22 μA in power-save mode - extends battery life in standby or low-activity states without sacrificing wake-up response. |
| Feedback Reference | 0.6 V ±1% - allows precise output programming via external resistor divider; supports OVT tracking down to 0.1 V. |
| Thermal Shutdown | 160°C with 20°C hysteresis - protects against sustained overload or poor heatsinking while allowing recovery without system reset. |
| Power Good Threshold | 95% of target VOUT rising, 90% falling - provides reliable sequencing signal for downstream regulators or processors. |
Pinout & Package
TPS62510DRCTG4 is housed in a thermally enhanced 3-mm × 3-mm, 10-pin VSON (DRC) package with exposed thermal pad connected to AGND. The package supports high-power density layouts and efficient heat dissipation in handheld applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW | Power switch node | Connects directly to inductor; carries high di/dt switching current - requires short, low-inductance trace routing. |
| PGND | Power ground return | Low-impedance path for high-current inductor return; must be separated from AGND except at single-point connection. |
| AGND | Analog ground reference | Reference for FB, OVT, EN, MODE, PG; connects to exposed thermal pad for noise-sensitive analog circuitry. |
| FB | Feedback voltage sense | Monitors output via resistor divider; regulates to 0.6 V internal reference - determines final VOUT accuracy and stability. |
| OVT | Output voltage tracking input | Overrides internal 0.6-V reference when driven below 0.6 V - enables coordinated startup with external rails (e.g., I/O before core). |
| EN | Enable control input | Active-high logic interface; must be terminated - floating state disables regulator and reduces IQ to 0.1 μA. |
| MODE | Operating mode select | High = forced 1.5-MHz PWM; Low = automatic PFM/PWM transition - selects between low-noise or wide-efficiency operation. |
| PG | Power good indicator | Open-drain output pulled low during disable or >10% VOUT droop - used for system sequencing or fault detection. |
| AVIN | Analog supply input | Filtered supply for control circuitry; decoupled via RC network to isolate switching noise from error amplifier and reference. |
| PVIN | Power stage input | Direct connection to input capacitor; supplies high-current path for P/N-channel MOSFETs - requires low-ESR bulk capacitance. |
Key Features
| Feature | Design Value |
|---|---|
| Output voltage tracking (OVT) | Enables precise sequencing of multiple rails by allowing VOUT to follow an external reference voltage below 0.6 V - critical for FPGA/core voltage ramp coordination. |
| 100% duty-cycle low-dropout mode | Maintains regulation even when VIN approaches VOUT - maximizes usable battery voltage range in 2-cell alkaline/NiMH systems. |
| Integrated dual MOSFET power stage | Eliminates need for external high-side switch and synchronous rectifier - reduces BOM count and layout complexity while ensuring matched timing. |
| Soft-start timing | 750 μs typical ramp time to 95% of target VOUT - limits inrush current and prevents input rail collapse during power-up. |
| Undervoltage lockout (UVLO) | 1.55 V threshold with 150-mV hysteresis on AVIN pin - prevents erratic operation during brownout conditions and ensures clean startup. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62506DRCT | Same 1.8–3.8-V input, 1.5-A rating, and VSON-10 package but fixed 1.2-V output; lacks OVT and MODE pins. | Suitable only for non-tracking, fixed-output applications where sequencing is handled externally. | Select when output voltage is fixed and OVT/MODE functionality is unnecessary - reduces design complexity and cost. |
| TPS62130ARGTR | Wider 3–17-V input range, 3-A output, 2.5-MHz switching; uses 16-pin QFN with different pinout and no OVT function. | Targets higher-input industrial or automotive systems, not low-voltage battery-powered devices. | Choose for higher input voltage or current requirements - not a drop-in replacement due to incompatible voltage range and package. |
Compared with TPS62510DRCTG4, TPS62506DRCT offers simplified fixed-output operation but forfeits sequencing flexibility, while TPS62130ARGTR scales performance for higher-power systems at the expense of battery-rail compatibility and pinout compatibility.

FAQ
What input voltage range does the TPS62510DRCTG4 support?
The TPS62510DRCTG4 supports an input voltage range of 1.8 V to 3.8 V, making it ideal for direct operation from two alkaline or NiMH cells, or from fixed 3.3-V, 2.5-V, or 1.8-V system rails. This range is validated across –40°C to 85°C ambient temperature and accounts for UVLO hysteresis and dropout behavior in 100% duty-cycle mode.
How does the OVT pin function in the TPS62510DRCTG4?
The OVT pin on the TPS62510DRCTG4 allows the output voltage to track an external reference voltage below 0.6 V, overriding the internal feedback reference. When an external voltage less than 0.6 V is applied to OVT, the TPS62510DRCTG4 regulates its output to match that voltage - enabling controlled power-up sequencing between core and I/O rails in FPGAs or processors.
What is the purpose of separating AVIN and PVIN on the TPS62510DRCTG4?
AVIN and PVIN are separated on the TPS62510DRCTG4 to isolate noise-sensitive analog circuitry (error amplifier, reference, comparators) from high-current power switching paths. AVIN supplies the control logic and must be filtered via an RC network, while PVIN delivers current to the integrated MOSFETs - this separation improves PSRR and maintains regulation accuracy under heavy load transients.
Does the TPS62510DRCTG4 support synchronization to an external clock?
Yes, the TPS62510DRCTG4 supports external clock synchronization via the MODE pin, accepting input frequencies from 1.15 MHz to 2.25 MHz aligned to the falling edge. This capability allows phase-shifted operation of multiple converters to reduce input RMS current and conducted EMI - confirmed in the Electrical Characteristics table and Functional Block Diagram.
What thermal protection features does the TPS62510DRCTG4 include?
The TPS62510DRCTG4 includes thermal shutdown that disables all switching activity when junction temperature exceeds 160°C (typical), with 20°C hysteresis for automatic recovery. This protection is independent of load current and ambient conditions, and is implemented in silicon - verified in Section 6.5 Electrical Characteristics and Section 7.3.4 of the datasheet.
