Product details
Overview
TPS62000YEGT from Texas Instruments is an adjustable-output synchronous step-down DC-DC converter optimized for low-power battery-powered systems. It delivers up to 600 mA output current with >95% peak efficiency, operates from 2 V to 5.5 V input, supports 0.8 V to VIN adjustable output, and features pin-programmable current limit (600 mA or 1.2 A) in a 10-pin VSSOP package - used in cellular phones, PDAs, and USB DSL modems.
For engineers reviewing the TPS62000YEGT datasheet, TPS62000YEGT pinout, TPS62000YEGT application, or TPS62000YEGT equivalent, key selection criteria include its PFM/PWM hybrid control mode, 50 µA typical quiescent current in power-save mode, 750 kHz nominal switching frequency, 100% duty-cycle dropout capability, and integrated antiringing switch (disabled in adjustable version).
Technical Context
The TPS62000YEGT implements current-mode control with internal slope compensation and a fixed-frequency PWM mode (750 kHz typical) that transitions to pulse-frequency modulation (PFM) below ~120 mA load to maintain high light-load efficiency. Its dual-MOSFET synchronous rectification eliminates external diode losses.
Control logic includes undervoltage lockout (~1.6 V), soft-start (~1 ms), power-good monitoring (92–94% VOUT threshold), and SYNC pin-configurable operation: GND enables PFM/PWM auto-switching, VIN forces fixed-frequency PWM, and external clock (500–1000 kHz) synchronizes switching while disabling PFM.
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 2–3-cell alkaline/NiMH systems without external LDO pre-regulation. |
| Output Voltage Range | 0.8 V to VIN - adjustable via external resistor divider; reference voltage is 0.45 V, enabling precise low-voltage core supply generation. |
| Max Output Current | 600 mA (ILIM = GND) or 1.2 A (ILIM = VIN) - selectable via single pin connection, allowing design flexibility across load profiles. |
| Quiescent Current | 50 µA typical (PFM mode) - enables multi-week battery life in always-on portable devices with intermittent active loads. |
| Switching Frequency | 750 kHz typical (free-running); 500–1000 kHz synchronizable - permits use of compact 10 µH inductors and reduces EMI filtering burden. |
| Efficiency Peak | 95% at 3.6 VIN/2.5 VOUT/200 mA - achieved via synchronous rectification and low RDS(on) P/N-channel MOSFETs (200–410 mΩ). |
| Power-Good Threshold | 92% of nominal VOUT - open-drain PG output provides reliable system reset signaling with 100 µs startup delay. |
Pinout & Package
TPS62000YEGT is housed in a 10-pin VSSOP (DGS) package measuring 3.00 mm × 3.00 mm, optimized for space-constrained portable PCB layouts. Thermal resistance is 160°C/W (junction-to-ambient) with 73°C/W junction-to-board performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Primary power input | Accepts 2–5.5 V; requires 10 µF ceramic bypass capacitor close to pin for stable high-frequency operation. |
| FC (Pin 2) | Input supply bypass | Connect 0.1 µF capacitor to ground for high-frequency noise suppression on input rail. |
| GND (Pin 3) | Analog ground reference | Low-noise reference for error amplifier and internal circuits; separate from PGND. |
| PG (Pin 4) | Power-good indicator | Open-drain output; requires external pull-up to VOUT; asserts high when VOUT ≥92% of target. |
| FB (Pin 5) | Feedback input | Connects to external resistor divider for adjustable output; internal 0.45 V reference sets VOUT = 0.45 × (1 + R1/R2). |
| ILIM (Pin 6) | Current-limit configuration | GND = 600 mA limit; VIN = 1.2 A limit - selects peak switch current without external components. |
| SYNC (Pin 7) | Mode control / sync input | GND = PFM/PWM auto-switching; VIN = forced PWM; external CMOS clock = synchronization (500–1000 kHz). |
| EN (Pin 8) | Enable control | Logic high enables regulator; logic low reduces supply current to <1 µA for full system shutdown. |
| 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 | High-current return path for internal MOSFETs and inductor; must be connected to PCB power plane with minimal impedance. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous rectification | Integrated P- and N-channel MOSFETs eliminate external Schottky diode, reducing conduction loss and board area. |
| Hybrid PFM/PWM control | Automatically switches between fixed-frequency PWM (moderate/heavy load) and variable-frequency PFM (light load) to sustain >85% efficiency down to 1 mA. |
| 100% duty-cycle operation | Enables dropout-free regulation when VIN approaches VOUT, maintaining output during brownout conditions without external circuitry. |
| Internal soft-start | ~1 ms ramp prevents output overshoot and inrush current during enable, eliminating need for external soft-start timing components. |
| Undervoltage lockout (UVLO) | ~1.6 V turn-on threshold prevents erratic startup from weak batteries, ensuring clean power sequencing in portable systems. |

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 |
|---|---|---|---|
| TPS62056RGTR | Higher 1.2-A rating, 2.5-V to 6-V input, 3-MHz fixed frequency, smaller 6-pin WSON package | Better suited for space-constrained designs requiring higher current and faster transient response | Select when board area is critical and input voltage exceeds 2.5 V; not drop-in due to different pinout and no ILIM/SYNC flexibility |
| TPS62231DRVR | 3-MHz operation, 2.05-V to 6-V input, 0.6-V to 5.5-V output, 600-mA rating, integrated soft-start | Optimized for ultra-small footprint and lower VIN start-up (2.05 V), but lacks SYNC and ILIM configuration pins | Choose for newer designs prioritizing miniaturization and simplified BOM; requires redesign for SYNC-based noise control or current-limit adjustment |
Compared with TPS62000YEGT, TPS62056RGTR offers higher frequency and current but sacrifices programmability and low-VIN compatibility, while TPS62231DRVR improves integration and size at the cost of flexible mode control - making TPS62000YEGT uniquely suitable for legacy battery-powered systems requiring configurable PFM/PWM behavior and wide input range.

FAQ
What is the minimum input voltage required for TPS62000YEGT to operate reliably?
The TPS62000YEGT has a specified minimum input voltage of 2 V and an undervoltage lockout threshold of approximately 1.6 V. Operation below 2 V may result in reduced output current capability or instability; for reliable regulation across temperature, maintain VIN ≥2 V. The device can sustain 100% duty cycle down to ~1.8 V input, but full functionality requires ≥2 V per datasheet specifications.
How does the ILIM pin affect current limiting in TPS62000YEGT?
The ILIM pin on the TPS62000YEGT configures the internal switch current limit: connecting ILIM to GND sets the limit to typically 600 mA, while connecting it to VIN raises it to typically 1.2 A. This selection directly determines maximum sustainable output current and influences inductor sizing and thermal design - no external components are needed to change the limit.
Can TPS62000YEGT be synchronized to an external clock, and what is the valid frequency range?
Yes, the TPS62000YEGT supports external clock synchronization via the SYNC pin. It accepts CMOS-level signals from 500 kHz to 1000 kHz. When synchronized, the device operates in forced PWM mode only - PFM is disabled - ensuring deterministic switching for EMI-sensitive applications like RF sections or audio subsystems.
What is the purpose of the FC pin on TPS62000YEGT, and how should it be decoupled?
The FC (Filter Capacitor) pin on TPS62000YEGT is a dedicated high-frequency input bypass terminal. It must be connected to a 0.1 µF ceramic capacitor placed as close as possible to the pin and to GND. This capacitor filters switching noise on the input rail, improving stability and reducing conducted EMI - omitting or misplacing this capacitor risks oscillation or degraded transient response.
Does TPS62000YEGT include an antiringing switch, and is it active in the adjustable-output version?
No, the antiringing switch in the TPS62000YEGT is explicitly disabled for the adjustable-output version (TPS62000). As stated in the datasheet Feature Description section 8.3.1, this function is only implemented in fixed-output variants (e.g., TPS62001–TPS62008) to suppress parasitic oscillations during discontinuous conduction mode. The TPS62000YEGT relies on external layout and component selection for EMI control.
