Product details
Overview
TLV62065DSGT from Texas Instruments is a synchronous step-down DC–DC converter delivering up to 2 A at 1.8 V output from 2.9–5.5 V input, operating at 3-MHz fixed frequency with automatic PFM/PWM mode transition, achieving up to 97% efficiency and featuring internal 100% duty-cycle operation for low-dropout battery applications.
For engineers reviewing the TLV62065DSGT datasheet, TLV62065DSGT pinout, TLV62065DSGT application, or TLV62065DSGT equivalent, key selection considerations include its 2×2 mm WSON-8 package, 18-µA quiescent current in PFM mode, ±2.0% output voltage accuracy in PWM mode, integrated high- and low-side MOSFETs with 95–150 mΩ and 75–100 mΩ RDS(on), and output capacitor discharge function during shutdown.
Technical Context
The TLV62065DSGT implements a fast-response voltage-mode control architecture with input voltage feed-forward, enabling stable regulation using small ceramic capacitors. Its dual-mode operation-forced 3-MHz PWM (via MODE pin high) or automatic PFM/PWM transition (MODE pin low)-supports both noise-sensitive and ultra-low-power use cases.
Internally, it integrates high- and low-side MOSFETs with cycle-by-cycle current limiting, thermal shutdown at 150°C, undervoltage lockout (1.78 V falling / 1.95 V rising), and soft-start with 500 µs typical start-up time. The feedback loop references a precise 600-mV internal bandgap, supporting adjustable outputs via external resistor divider.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 2.9 V to 5.5 V - supports direct regulation from single-cell Li-ion (3.0–4.2 V) or 3.3/5-V system rails without pre-regulation. |
| IOUT Max | 2 A - sufficient for powering core logic, FPGAs, or DDR memory subsystems in portable devices. |
| fSW | 2.6–3.4 MHz (typ. 3 MHz) - enables use of sub-2-mm inductors (e.g., 1.0 µH) and compact 0603 ceramic capacitors. |
| Efficiency | Up to 97% - achieved at mid-load with 3.7-V input and 1.8-V/2-A output, minimizing thermal load in space-constrained designs. |
| IQ (PFM) | 18 µA - extends battery runtime in standby or light-load states such as sensor polling or RTC operation. |
| VFB Accuracy | ±2.0% in PWM mode - ensures tight output regulation critical for voltage-sensitive processors and analog circuitry. |
| RDS(on) HS/L | 95–150 mΩ / 75–100 mΩ - reduces conduction loss and improves full-load efficiency over wide input range. |
| Shutdown ISD | <1 µA - fully isolates power path and prevents battery drain during system sleep or off-state. |
Pinout & Package
TLV62065DSGT is housed in an 8-pin 2.00 mm × 2.00 mm × 0.75 mm WSON package with exposed thermal pad (DSG suffix), requiring PCB land pattern connection to GND for optimal thermal performance and EMI control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PVIN | Power input for high-current switch stage | Connects directly to input capacitor and high-side MOSFET source; must be low-inductance path to minimize switching noise. |
| PGND | Power ground return for switch stage | Provides dedicated return path for inductor current; separate from AGND to avoid coupling noise into control circuitry. |
| SW | Switch node | Drives external inductor; requires short, low-area trace to reduce EMI and ringing; connects to both MOSFETs internally. |
| AVIN | Analog supply for control circuitry | Must tie to PVIN and local 10-µF ceramic capacitor; powers error amplifier, reference, and logic-noise-sensitive node. |
| AGND | Analog ground reference | Reference point for FB, EN, MODE, and internal circuits; connect to PGND only at single point near thermal pad. |
| FB | Feedback input | Monitors output via resistor divider; internal 600-mV reference enables precise adjustable output (e.g., 1.8 V with 360 kΩ/180 kΩ). |
| EN | Enable control | Active-high logic input; pulling low disables converter and activates internal SW-to-PGND discharge resistor (~200 Ω). |
| MODE | Operating mode select | Low = auto PFM/PWM transition; high = forced 3-MHz PWM-used to suppress switching noise in audio or RF sections. |
Key Features
| Feature | Design Value |
|---|---|
| 100% Duty Cycle Operation | Enables dropout as low as VOUT + IOUT × (RDS(on) + RL) - maximizes usable battery voltage range in single-cell Li-ion systems. |
| Output Capacitor Discharge | Internal ~200-Ω resistor connects SW to PGND in shutdown - eliminates floating output voltage and ensures monotonic startup. |
| Fast Voltage-Mode Control | Input-voltage feed-forward and optimized compensation - achieves stable regulation with 1-µH inductor and 10-µF ceramic output cap, no external compensation required. |
| Integrated Current Limiting | Programmable high-/low-side MOSFET current limit (2.3–2.75 A typ.) with foldback during overload - protects against short-circuit without external sensing. |
| Thermal Shutdown with Hysteresis | Triggers at 150°C junction temperature with 10°C hysteresis - prevents thermal runaway while allowing recovery without system reset. |
| Ultra-Low Quiescent Current | 18 µA in PFM mode - reduces no-load power loss by >90% vs. fixed-frequency alternatives, extending shelf life in always-on devices. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62065DSGT | Same pinout, identical electrical specs, but rated for –40°C to 125°C junction temperature (vs. TLV62065DSGT's –40°C to 125°C); identical WSON-8 package. | Targeted at automotive under-hood or industrial high-temp environments where extended TJ rating is mandatory. | Select TPS62065DSGT when operation above 85°C ambient is required; otherwise TLV62065DSGT meets commercial/industrial needs. |

FAQ
What is the recommended inductor value for TLV62065DSGT in a 1.8-V/2-A application?
The TLV62065DSGT is optimized for a 1.0-µH inductor (e.g., Murata LQM32PN or Taiyo Yuden NRG4026T). This value balances ripple current, transient response, and size. Inductor saturation current must exceed 2.75 A, and DC resistance should be minimized to preserve efficiency. Using 1.2 µH is acceptable but increases size without significant benefit at 2-A load.
Does TLV62065DSGT require external compensation components?
No, TLV62065DSGT features internal compensation optimized for 1-µH inductors and 10–22-µF ceramic output capacitors. No external compensation network is needed. However, an external feed-forward capacitor (Cff = 22 pF) between FB and output is required for optimal loop stability and transient performance per the datasheet.
How does the MODE pin affect efficiency and noise in TLV62065DSGT operation?
When MODE is low, TLV62065DSGT enters automatic PFM/PWM mode-delivering >90% efficiency down to 100 µA load via variable-frequency pulse skipping. When MODE is high, it forces fixed 3-MHz PWM, increasing light-load losses (e.g., ~75% at 1 mA) but enabling predictable EMI filtering. Noise-sensitive circuits (e.g., audio ADCs) benefit from forced PWM.
Can TLV62065DSGT operate with input voltage below 2.9 V?
No-TLV62065DSGT has a hard undervoltage lockout threshold of 1.78 V (falling) and 1.95 V (rising), but its specified minimum operating input is 2.9 V. Below 2.9 V, output regulation cannot be guaranteed due to insufficient headroom for 100% duty cycle and internal bias requirements. For sub-2.9-V inputs, consider TI's TPS6208x series.
What is the purpose of the exposed thermal pad on TLV62065DSGT?
The exposed thermal pad on TLV62065DSGT must be soldered to a PCB copper pour connected to PGND. It serves two critical functions: (1) dissipating heat-reducing junction-to-board thermal resistance to 34.5°C/W-and (2) providing a low-inductance, low-resistance ground return path for the power stage, essential for EMI control and stable switching behavior.
