Product details
Overview
TPS62000YEGR from Texas Instruments is an adjustable-output synchronous step-down DC-DC converter optimized for low-power portable systems. It delivers up to 600 mA output current, operates from 2 V to 5.5 V input, supports 0.8 V to VIN output range, features 750 kHz typical switching frequency, and achieves >95% peak efficiency at 3.6 VIN/2.5 VOUT. It is used in battery-powered handheld devices requiring high light-load efficiency and compact power solutions.
For engineers reviewing the TPS62000YEGR datasheet, TPS62000YEGR pinout, TPS62000YEGR application, or TPS62000YEGR equivalent, key selection criteria include its PFM/PWM hybrid control mode, pin-programmable current limit (600 mA/1.2 A), 50 μA quiescent current in power-save mode, 10-pin VSSOP package, and support for external synchronization up to 1 MHz.
Technical Context
The TPS62000YEGR implements a current-mode synchronous buck architecture with integrated P-channel high-side and N-channel low-side MOSFETs. Its control loop uses internal compensation and soft-start (1 ms typical), enabling stable operation with minimal external components. The device transitions between fixed-frequency PWM (750 kHz) at moderate loads and variable-frequency PFM at light loads to maintain high efficiency down to microampere-level output currents.
It supports three functional modes via the SYNC pin: GND enables PFM/PWM auto-switching; VIN forces continuous PWM; and external CMOS clock (500–1000 kHz) synchronizes switching while disabling PFM. The ILIM pin selects current limit thresholds (600 mA or 1.2 A), and the FB pin accepts an external resistor divider to set output voltage from 0.8 V to VIN with 0.45 V internal reference.
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 batteries without pre-regulation. |
| Output Voltage Range | 0.8 V to VIN - adjustable via external resistor divider; 0.45 V internal reference enables precise low-voltage rail generation. |
| Max Output Current | 600 mA - achievable with ILIM tied to GND; sufficient for low-power CPUs, DSPs, and USB peripherals. |
| Quiescent Current | 50 μA (typ) - enables >90% efficiency at 1 mA load, critical for standby and sleep-mode battery life. |
| Switching Frequency | 750 kHz (typ), 500–1000 kHz sync range - allows use of small 10 μH inductors and ceramic capacitors in space-constrained designs. |
| Efficiency Peak | 95% - measured at 3.6 VIN/2.5 VOUT/200 mA, confirming suitability for thermally sensitive portable applications. |
| Shutdown Current | 0.1 μA (typ) - reduces system leakage during full power-down, extending shelf life in always-on devices. |
Pinout & Package
The TPS62000YEGR is housed in a 10-pin VSSOP (DGS) package measuring 3.00 mm × 3.00 mm, optimized for high-density PCB layouts in portable electronics.
| 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) | Supply bypass | High-frequency input filter node; must be decoupled with 0.1 μF capacitor placed adjacent to pin. |
| GND (Pin 3) | Analog ground | Reference for internal error amplifier and comparator; separate from PGND to minimize noise coupling. |
| PG (Pin 4) | Power-good open-drain output | Signals valid regulation when VOUT ≥92% nominal; requires external pull-up to VOUT or system rail. |
| FB (Pin 5) | Feedback input | Connects to external resistor divider; internal 0.45 V reference sets output voltage per VOUT = 0.45 × (1 + R1/R2). |
| ILIM (Pin 6) | Current-limit select | Tie to GND for 600 mA limit or to VIN for 1.2 A limit; configures overcurrent protection threshold. |
| SYNC (Pin 7) | Mode control/synchronization | GND enables PFM/PWM auto-switching; VIN forces PWM-only; external 500–1000 kHz clock synchronizes switching. |
| EN (Pin 8) | Enable input | Active-high logic; <0.4 V disables device, reducing IQ to <1 μA; VIH ≥1.3 V required for turn-on. |
| 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 switch node and internal MOSFETs; must be connected to main PCB ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| PFM/PWM Hybrid Control | Maintains >90% efficiency from 100 μA to 600 mA load by automatically switching between pulse-frequency and pulse-width modulation. |
| 100% Duty-Cycle Operation | Enables dropout <100 mV at light loads when VIN ≈ VOUT, supporting ultra-low-voltage operation near battery end-of-life. |
| Internal Soft-Start | 1 ms typical ramp prevents output overshoot and inrush current during power-up, eliminating need for external timing components. |
| Antiringing Switch (Fixed-VOUT only) | Reduces EMI in DCM by clamping inductor flyback energy; not active on TPS62000YEGR due to adjustable output configuration. |
| Undervoltage Lockout | Disables operation below ~1.6 V VIN, preventing erratic behavior during brownout or deep battery discharge. |

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 |
|---|---|---|---|
| TPS62040DRVR | Higher 2-MHz switching frequency, 1.2-A output, smaller 6-pin WSON package; lacks SYNC and PG pins. | Better suited for ultra-compact, high-frequency designs where size trumps feature count; no power-good monitoring or clock sync. | Select when board space is critical and PFM/PWM flexibility or system-level power sequencing is not required. |
| TPS62231DRYR | 3-MHz operation, 600-mA output, 1.5-μA quiescent current in shutdown, but fixed 1.8-V output only; no adjustable option. | Ideal for cost-sensitive, single-rail applications like memory I/O or sensor interfaces where output voltage is invariant. | Choose when fixed 1.8 V is acceptable and lowest possible shutdown current (<1.5 μA) is prioritized over adjustability. |
Compared with TPS62040DRVR and TPS62231DRYR, the TPS62000YEGR offers unique adjustability, comprehensive system control (SYNC, PG, ILIM), and proven PFM/PWM efficiency across wide load ranges-making it optimal for multi-rail, battery-critical portable systems requiring design flexibility and long runtime.

FAQ
What is the output voltage adjustment range of the TPS62000YEGR?
The TPS62000YEGR supports an adjustable output voltage range from 0.8 V to VIN using an external resistor divider connected to the FB pin. Its internal 0.45 V reference enables precise low-voltage rails; for example, with R1 = 820 kΩ and R2 = 180 kΩ, the output is set to 2.5 V. The total divider resistance must not exceed 1 MΩ to ensure loop stability.
How does the TPS62000YEGR manage efficiency at light loads?
The TPS62000YEGR maintains high efficiency at light loads by automatically entering pulse-frequency modulation (PFM) mode when output current drops below ~120 mA for more than 15 cycles. In this mode, it reduces switching frequency and holds constant peak inductor current (~150 mA + 50 mA/V × (VIN – VOUT)), lowering quiescent current to 50 μA (typ) and sustaining >90% efficiency down to 100 μA load.
Can the TPS62000YEGR be synchronized to an external clock?
Yes, the TPS62000YEGR can be synchronized to an external CMOS-level clock signal applied to the SYNC pin across a 500 kHz to 1 MHz range. When synchronized, the device operates in forced PWM mode, disabling PFM to ensure fixed-frequency operation-critical for noise-sensitive applications like audio codecs or RF subsystems where variable switching frequency could cause interference.
What is the purpose of the ILIM pin on the TPS62000YEGR?
The ILIM pin on the TPS62000YEGR selects the internal current limit threshold: tying ILIM to GND sets the switch current limit to 600 mA (typ), while connecting it to VIN raises the limit to 1.2 A (typ). This allows designers to optimize overcurrent protection for specific inductor and layout constraints without changing the IC, supporting both compact and high-current implementations.
Does the TPS62000YEGR include power-good signaling?
Yes, the TPS62000YEGR provides a dedicated open-drain power-good (PG) output that asserts high when the output voltage reaches ≥92% of its nominal value. The PG signal is only valid after a 100 μs delay following EN activation and requires an external pull-up resistor to VOUT or another system rail. It enables safe power sequencing and system reset assertion in portable electronics.
