Product details
Overview
TPS62000DGSG4 from Texas Instruments is an adjustable-output, synchronous step-down DC-DC converter optimized for low-power portable systems. It operates from 2 V to 5.5 V input, delivers up to 600 mA output current, achieves >95% peak efficiency at 3.6 VIN/2.5 VOUT, and features pin-programmable current limit (600 mA or 1.2 A) in a 10-pin VSSOP package. It powers core logic in battery-powered handheld devices requiring stable, low-noise regulation.
For engineers reviewing the TPS62000DGSG4 datasheet, TPS62000DGSG4 pinout, TPS62000DGSG4 application, or TPS62000DGSG4 equivalent, key selection factors include its PFM/PWM hybrid control mode, 50 μA typical quiescent current in power-save mode, 750 kHz nominal switching frequency, 0.8 V to VIN adjustable output range, and support for external synchronization up to 1 MHz.
Technical Context
The TPS62000DGSG4 implements current-mode control with internal slope compensation and a fixed 750 kHz oscillator that can be synchronized externally (500–1000 kHz). Its dual-MOSFET synchronous rectification eliminates the need for an external diode and enables 100% duty-cycle operation near dropout.
It integrates soft-start (1 ms typical), undervoltage lockout (~1.6 V), and a power-good open-drain output with 92% threshold hysteresis. The FB pin accepts an external resistor divider for output voltage setting, while ILIM selects between 600 mA and 1.2 A switch current limits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2 V to 5.5 V - supports single-cell Li-ion (2.7–4.2 V) and multi-cell alkaline/NiMH (2–5.5 V) battery inputs. |
| Output Voltage Range | 0.8 V to VIN - adjustable via external resistor divider; enables precise core voltage scaling for low-voltage processors. |
| Max Output Current | 600 mA - sufficient for powering DSPs, microcontrollers, and RF ICs in portable electronics without thermal derating. |
| Quiescent Current | 50 μA (typ) - enables ultra-low standby power in always-on subsystems such as real-time clocks or sensor interfaces. |
| Switching Frequency | 750 kHz (nominal) - allows use of compact 10 μH inductors and low-ESR ceramic capacitors for space-constrained PCB layouts. |
| Efficiency Peak | 95% - achieved at 3.6 VIN/2.5 VOUT/200 mA, minimizing heat generation and extending battery runtime. |
| Shutdown Current | 0.1 μA (max) - ensures negligible battery drain during system sleep or off-state. |
Pinout & Package
TPS62000DGSG4 is housed in a 10-pin VSSOP (DGS) package measuring 3.00 mm × 3.00 mm, with exposed thermal pad for enhanced power dissipation in compact portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Power input | Accepts 2–5.5 V supply; requires 10 μF input capacitor for stability and ripple suppression. |
| FC (Pin 2) | Input bypass | High-frequency decoupling node; must connect 0.1 μF capacitor close to pin for noise immunity. |
| GND (Pin 3) | Analog ground | Reference for control circuitry; separate from PGND to minimize noise coupling into feedback path. |
| PG (Pin 4) | Power-good indicator | Open-drain output active high when VOUT ≥92% of nominal; requires external pull-up for system sequencing. |
| FB (Pin 5) | Feedback input | Connects to external resistor divider to set output voltage; internal reference is 0.45 V. |
| ILIM (Pin 6) | Current limit select | GND = 600 mA limit; VIN = 1.2 A limit - configures overcurrent protection without external components. |
| SYNC (Pin 7) | Mode control | GND = PFM/PWM auto-switching; VIN = forced PWM; external clock = sync mode (500–1000 kHz). |
| EN (Pin 8) | Enable input | Active-high logic control; <1 μA shutdown current when pulled low - enables system-level power gating. |
| L (Pin 9) | Switch node | Connects to inductor; carries high di/dt switching current - requires short, low-inductance trace routing. |
| PGND (Pin 10) | Power ground | Return path for high-current switches; must be connected separately to GND plane under IC for EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous rectification | Integrated P-channel and N-channel MOSFETs eliminate external diode, reducing conduction loss and board area. |
| PFM/PWM hybrid control | Maintains >85% efficiency down to 1 mA load by automatically switching to pulse-frequency modulation at light loads. |
| Antiringing switch (disabled for TPS62000) | Not active in adjustable version - avoids unnecessary complexity; fixed-output variants use it to suppress DCM ringing. |
| Internal soft-start | 1 ms typical ramp prevents output overshoot and inrush current during power-up, protecting downstream circuitry. |
| 100% duty-cycle operation | Enables LDO-like behavior near dropout (VIN ≈ VOUT), sustaining regulation even as battery discharges to 2.0 V. |

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 |
|---|---|---|---|
| TPS62040DRCR | Higher 2-MHz switching frequency; 1.2-A output; smaller 10-pin WSON package; no SYNC pin. | Better suited for space-critical apps needing faster transient response; lacks external clock sync for EMI control. | Choose TPS62040DRCR if board area is constrained and sync capability is unnecessary. |
| TPS62231DRVR | 3-MHz operation; 600-mA output; integrated soft-start; 20-μA IQ; fixed 1.8-V or 3.3-V options only. | Optimized for ultra-low-IQ always-on rails; no adjustable output or ILIM pin - less flexible for multi-rail systems. | Choose TPS62231DRVR for dedicated low-quiescent fixed-rail supplies where adjustability isn't required. |
Compared with TPS62040DRCR and TPS62231DRVR, the TPS62000DGSG4 uniquely balances adjustability, sync capability, and proven 750-kHz efficiency across 2–5.5 V inputs - making it optimal for legacy portable designs requiring field-proven reliability and flexible voltage programming.

FAQ
What is the output voltage adjustment range supported by the TPS62000DGSG4?
The TPS62000DGSG4 supports an adjustable output voltage range from 0.8 V up to the input voltage (VIN). This is achieved using an external resistor divider connected to the FB pin, referenced to an internal 0.45 V bandgap. The device's datasheet specifies ±3% output accuracy over temperature and line/load conditions, enabling precise core voltage tuning for low-power processors and ASICs.
How does the TPS62000DGSG4 manage efficiency at light loads?
The TPS62000DGSG4 uses automatic PFM/PWM mode switching to maintain high efficiency across load currents. Below ~120 mA, it enters pulse-frequency modulation (PFM) mode-reducing switching frequency and holding peak inductor current constant-achieving >85% efficiency at 1 mA. At higher loads, it transitions seamlessly to fixed-frequency PWM operation at 750 kHz, ensuring consistent regulation and low output ripple.
Can the TPS62000DGSG4 be synchronized to an external clock, and what is the valid frequency range?
Yes, the TPS62000DGSG4 can be synchronized to an external CMOS-level clock applied to the SYNC pin. The valid synchronization range is 500 kHz to 1000 kHz. When synchronized, the device disables PFM mode and operates exclusively in forced PWM mode, enabling deterministic switching for EMI filtering and noise-sensitive applications like audio or imaging subsystems.
What is the purpose of the ILIM pin on the TPS62000DGSG4, and how is it configured?
The ILIM pin on the TPS62000DGSG4 sets the internal switch current limit. Connecting ILIM to GND configures a typical 600 mA limit; connecting it to VIN selects a typical 1.2 A limit. This pin provides hardware-selectable overcurrent protection without external components, allowing designers to optimize inductor sizing and thermal design based on expected peak load requirements in the target application.
Does the TPS62000DGSG4 include built-in protection features, and which ones are implemented?
Yes, the TPS62000DGSG4 integrates multiple protection functions: undervoltage lockout (~1.6 V turn-on threshold), thermal shutdown, cycle-by-cycle current limiting, and soft-start (1 ms typical). It also features a power-good (PG) open-drain output with 92% threshold hysteresis and a 100 μs startup delay to prevent false assertions. These features ensure robust operation in battery-powered systems subject to voltage sag and thermal stress.
