Product details
Overview
TPS62063DSGT from Texas Instruments is a fixed-output 3.3-V, 1.6-A synchronous step-down DC-DC converter in an 8-pin WSON package. It operates from 2.7 V to 6 V input, delivers up to 97% efficiency at 1.6 A, supports auto PFM/PWM mode switching, and features 100% duty cycle low-dropout operation for Li-ion battery applications.
For engineers reviewing the TPS62063DSGT datasheet, TPS62063DSGT pinout, TPS62063DSGT application, or TPS62063DSGT equivalent, key selection criteria include its 3-MHz fixed switching frequency, ±1.5% output voltage accuracy in PWM mode, 18-µA quiescent current, integrated output discharge, and thermal shutdown with 150°C trip point.
Technical Context
The TPS62063DSGT implements a voltage-mode control architecture with input voltage feed-forward for fast line/load regulation. Its internal 0.6-V reference enables precise 3.3-V output via factory-trimmed feedback network - no external resistors required.
It integrates high-side and low-side MOSFETs (RDS(on) ≤150 mΩ / ≤100 mΩ at 5 V), supports dynamic voltage positioning (1% overregulation in PFM mode), and includes clock dithering to suppress EMI harmonics. Shutdown current is <1 µA with active output capacitor discharge via internal SW-to-PGND resistor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7 V to 6 V - supports single-cell Li-ion (2.7–4.2 V) and 3.3/5-V system rails without external LDO pre-regulation. |
| Output Voltage | Fixed 3.3 V ±1.5% in PWM mode - eliminates external feedback divider, reduces BOM count and layout area. |
| Max Output Current | 1.6 A continuous - sufficient for powering DSP cores, FPGA I/O banks, or USB PHYs directly. |
| Switching Frequency | 3 MHz (±13%) - enables use of compact 1-µH inductors and 10-µF ceramic capacitors for <25-mm² total solution size. |
| Efficiency Peak | Up to 97% at 1.6 A - minimizes thermal rise in space-constrained portable designs like media players and pocket PCs. |
| Quiescent Current | 18 µA typical in PFM mode - extends battery runtime during standby/sleep states without compromising wake-up response. |
| Shutdown Current | 0.1 µA to 1 µA - ensures negligible drain on backup batteries or energy-harvesting sources during system off-state. |
Pinout & Package
TPS62063DSGT uses an 8-pin, 2.0 mm × 2.0 mm × 0.75 mm WSON package with exposed PowerPAD™ for thermal dissipation. The package is RoHS-compliant and moisture-sensitive level 2 (MSL-2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PGND (Pin 1) | Power Ground | Return path for high-current switch node; must be connected to low-impedance ground plane under PowerPAD™. |
| SW (Pin 2) | Switch Node | Connects to inductor; carries high di/dt switching current - requires short, wide trace and adjacent ground pour. |
| AGND (Pin 3) | Analog Ground | Reference for control circuitry; must be star-connected to PGND at single point near PowerPAD™ to avoid noise coupling. |
| FB (Pin 4) | Feedback Input | Internally tied to 3.3-V output - no external resistor divider needed; decoupling capacitor recommended at pin. |
| EN (Pin 5) | Enable Control | Active-high logic input; pulling low disables converter and activates internal SW-to-PGND discharge resistor (~1450 Ω). |
| MODE (Pin 6) | Operation Mode Select | Low = auto PFM/PWM; high = forced 3-MHz PWM - used to suppress audible noise or meet EMI filter requirements. |
| AVIN (Pin 7) | Analog Supply | Bias supply for control circuit; must be connected to PVIN and local 10-µF ceramic capacitor for stability. |
| PVIN (Pin 8) | Power Input | Main input power rail; connects to bulk input capacitor and AVIN - shared with high-current path to SW node. |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic Voltage Positioning | Maintains output at 3.33 V (1% above nominal) in PFM mode to absorb load-step undershoot without external compensation. |
| 100% Duty Cycle Operation | Enables dropout as low as 120 mV at 1.6 A (based on RDS(on) + inductor DCR), extending usable battery range down to ~3.4 V. |
| Integrated Output Discharge | Internal 75–1450 Ω resistor between SW and PGND discharges output capacitor within milliseconds after EN deactivation. |
| Thermal Shutdown with Hysteresis | Shuts down at 150°C junction temperature and resumes only after cooling to 140°C - prevents thermal runaway during overload. |
| Clock Dithering | ±6 ns frequency modulation spreads EMI energy across 2.6–3.4 MHz band, easing compliance with CISPR-22 Class B radiated emissions limits. |
Applications
| Point-of-Load Regulation | Notebook Subsystem Power |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62061DSGT | Fixed 1.8-V output; identical pinout, package, and electrical specs except output voltage and FB network. | Targets core logic rails (e.g., ARM Cortex-M3/M4 cores) instead of I/O or peripheral rails. | Select when system requires 1.8-V instead of 3.3-V; no PCB changes needed - direct drop-in replacement with voltage change only. |
| TPS62130ARGTR | 3-MHz, 3-A adjustable-output buck; larger 16-pin QFN package; higher current, wider VIN (3–17 V), no integrated discharge. | Suitable for higher-power subsystems (e.g., Wi-Fi modules) where 3.3-V/1.6-A is insufficient. | Choose when >1.6 A or >6-V input is required; requires new layout due to different pin count, package size, and lack of discharge function. |
Compared with TPS62061DSGT, the TPS62063DSGT provides higher output voltage for I/O interfaces but same efficiency and footprint; versus TPS62130ARGTR, it offers smaller size and integrated discharge at lower current rating - ideal for space-constrained 3.3-V POL applications.

FAQ
What is the output voltage tolerance of the TPS62063DSGT in PWM mode?
The TPS62063DSGT guarantees ±1.5% output voltage accuracy in forced PWM mode across temperature (–40°C to 85°C), input voltage (2.7 V to 6 V), and load (0–1.6 A). This specification is verified per TI's SLVSA95B datasheet Section 7.5, ensuring reliable 3.3-V regulation for sensitive I/O interfaces without external trimming. The TPS62063DSGT achieves this via factory-trimmed internal feedback network referenced to a 0.6-V bandgap.
Does the TPS62063DSGT require external feedback resistors to set its 3.3-V output?
No, the TPS62063DSGT does not require external feedback resistors. Its 3.3-V output is factory-programmed using an internal precision resistor divider connected to the FB pin. This eliminates BOM cost, layout area, and resistor tolerance errors - a key differentiator from adjustable variants like TPS62060. The TPS62063DSGT's FB pin is internally terminated and must be bypassed with a 10-nF ceramic capacitor to AGND per layout guidelines.
How does the TPS62063DSGT handle output capacitor discharge during shutdown?
When the EN pin is pulled low, the TPS62063DSGT enters shutdown mode and activates an internal discharge path between the SW pin and PGND. This path uses a programmable resistor (75–1450 Ω, typ. 200 Ω) to safely bleed the output capacitor to <100 mV within ~10 ms for a 10-µF COUT. This feature is confirmed in Section 7.5 (Electrical Characteristics) and Figure 6 of the SLVSA95B datasheet - critical for systems requiring rapid power-down compliance per safety standards.
Can the TPS62063DSGT operate with a 1-µH inductor and 10-µF output capacitor?
Yes, the TPS62063DSGT is explicitly optimized for 1-µH inductors and 10-µF ceramic output capacitors, as stated in the "Description" section and Section 9.2.2.2 of the SLVSA95B datasheet. This combination achieves optimal loop stability, <20-mV output ripple at full load, and minimal solution footprint (<25 mm²). Using larger values may degrade transient response or require compensation adjustments - the TPS62063DSGT's internal compensation is tuned for this exact LC pair.
What thermal performance can be expected from the TPS62063DSGT in its WSON package?
The TPS62063DSGT in the DSG (WSON-8) package has a junction-to-ambient thermal resistance (RθJA) of 64.68°C/W under JEDEC-standard high-K board conditions. With 1.6-A load and 97% efficiency at 4.2-V input, power dissipation is ~150 mW - resulting in ~10°C junction-to-ambient rise above ambient. Full derating guidance is provided in Section 7.6, confirming 1300 mW maximum power at 25°C ambient with 13 mW/°C linear derating above that point.
