Product details
Overview
TPS62000YZGR from Texas Instruments is an adjustable-output synchronous step-down DC-DC converter optimized for low-power portable systems, delivering up to 600 mA output current with >95% peak efficiency at 3.6 V input/2.5 V output, operating from 2 V to 5.5 V input, and featuring pin-programmable current limit (600 mA or 1.2 A) and PFM/PWM mode selection via SYNC pin.
For engineers reviewing the TPS62000YZGR datasheet, TPS62000YZGR pinout, TPS62000YZGR application, or TPS62000YZGR equivalent, key selection considerations include its 10-pin VSSOP package, 750 kHz typical switching frequency, 50 µA quiescent current in power-save mode, 100% duty-cycle dropout capability, and support for external synchronization up to 1 MHz.
Technical Context
The TPS62000YZGR implements a current-mode PFM/PWM control architecture with internal slope compensation and soft-start. It integrates high-side P-channel and low-side N-channel MOSFETs, enabling synchronous rectification without external diodes.
Its functional modes are determined by the SYNC pin: grounded for automatic PFM/PWM transition (high light-load efficiency), tied to VIN for forced PWM (fixed 750 kHz, low EMI filtering), or driven by an external 500–1000 kHz clock for system-level timing alignment. The ILIM pin 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 without external regulation. |
| Output Voltage Range | 0.8 V to VIN - adjustable via external resistor divider; enables precise core voltage scaling for low-power CPUs/DSPs. |
| Max Output Current | 600 mA - specified at VIN ≥2.5 V with 10 µH inductor; sufficient for baseband processors and RF front-ends in handheld devices. |
| Quiescent Current | 50 µA (typ) - enables >100-hour standby in battery-powered PDAs and MP3 players with minimal self-discharge. |
| Switching Frequency | 750 kHz (typ), 500–1000 kHz sync range - allows compact 10 µH inductors and 10 µF ceramic output capacitors, reducing board area. |
| Efficiency | 95% (typ) at 3.6 VIN/2.5 VOUT/200 mA - minimizes thermal rise in sealed enclosures and extends battery runtime. |
| Shutdown Current | 0.1 µA (typ) - ensures negligible battery drain during deep sleep or power-off states. |
Pinout & Package
TPS62000YZGR is housed in a 10-pin VSSOP (DGS) package measuring 3.00 mm × 3.00 mm, optimized for space-constrained portable PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Power input | Main supply rail connection; accepts 2–5.5 V; requires 10 µF bypass capacitor on FC pin. |
| FC | Input bypass | High-frequency decoupling node; must be connected to 0.1 µF capacitor near VIN for stable operation. |
| GND | Analog ground | Reference for internal error amplifier and feedback circuitry; separate from PGND to minimize noise coupling. |
| PG | Power-good open-drain | Signals valid output (≥92% VOUT) after 100 µs startup delay; requires external pull-up to VOUT. |
| FB | Feedback input | Connects to external resistor divider for adjustable output; internal reference is 0.45 V. |
| PGND | Power ground | Return path for high-current switch node (L); must be routed separately from GND and tied at single point. |
| L | Switch node | Drain connection of internal P-channel and source of N-channel MOSFETs; drives external 10 µH inductor. |
| EN | Enable control | Active-high logic input; <0.4 V disables device, reducing supply current to <1 µA. |
| SYNC | Mode/sync control | GND = PFM/PWM auto-switching; VIN = forced PWM; external CMOS clock = synchronization (500–1000 kHz). |
| ILIM | Current limit select | GND = 600 mA limit; VIN = 1.2 A limit - sets peak inductor current threshold for overcurrent protection. |
Key Features
| Feature | Design Value |
|---|---|
| PFM/PWM Hybrid Control | Maintains >85% efficiency down to 1 mA load via automatic mode switching, eliminating need for external load-detection circuitry. |
| 100% Duty-Cycle Operation | Enables dropout as low as 100 mV at full load, supporting ultra-low-VOUT applications like sub-1 V FPGA cores without input voltage headroom penalty. |
| Integrated Soft-Start | 1 ms internal ramp prevents output overshoot and inrush current spikes during power-up, protecting downstream LDOs and capacitors. |
| Antiringing Switch (Fixed-VOUT only) | Not active in TPS62000YZGR - this adjustable variant relies on external layout and component selection for EMI control in DCM. |
| Undervoltage Lockout | Activates below ~1.6 V VIN, preventing erratic startup or brownout operation in weak battery conditions. |

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 |
|---|---|---|---|
| TPS62060DSGR | Higher 2-MHz switching frequency, 1.2-A output, smaller 6-pin WSON package; lacks SYNC and ILIM pins. | Better suited for ultra-thin devices requiring <1 mm height; not pin-compatible due to different pin count and function mapping. | Select when board space is critical and fixed 2-MHz operation suffices; verify thermal performance at 1.2 A continuous load. |
| TPS62231DRVR | 3-MHz operation, 600-mA output, integrated soft-start and power-good; no ILIM pin; uses different feedback reference (0.6 V). | Optimized for rapid design cycles with fewer external components; lacks programmable current limit and sync capability. | Prefer for cost-sensitive consumer electronics where 3-MHz switching enables 4.7-µH inductors and eliminates need for external sync sources. |
Compared with TPS62060DSGR and TPS62231DRVR, the TPS62000YZGR offers unique flexibility in current-limit configuration and external clock synchronization-critical for noise-sensitive or thermally constrained industrial handhelds where adaptive PFM/PWM and system-level timing alignment are required.

FAQ
What is the recommended inductor value for TPS62000YZGR?
The TPS62000YZGR is optimized for a 10 µH inductor, as specified in the datasheet for stable operation across its full load and input voltage range. Using values outside 10–22 µH may cause instability or reduced efficiency. For TPS62000YZGR designs targeting >1.8 V output, a 22 µH inductor can improve light-load efficiency but requires verification of transient response. Always select inductors rated for ≥600 mA DC current and low DCR to maximize TPS62000YZGR efficiency.
How does the SYNC pin affect TPS62000YZGR efficiency and noise performance?
The SYNC pin directly controls TPS62000YZGR's operating mode: grounding it enables automatic PFM/PWM switching for highest light-load efficiency (>85% at 1 mA), while tying it to VIN forces fixed-frequency PWM for predictable EMI filtering. External synchronization (500–1000 kHz) aligns switching edges with system clocks to avoid beat frequencies. In forced PWM mode, TPS62000YZGR efficiency drops at light loads but delivers lower broadband noise-critical for audio or RF sections sharing the same PCB.
Can TPS62000YZGR operate with input voltage below 2 V?
No-TPS62000YZGR has a minimum recommended input voltage of 2 V per datasheet Section 7.3. Although the absolute maximum rating allows –0.3 V, operation below 2 V risks undervoltage lockout activation (typical threshold 1.6 V) and unstable regulation. The device is not characterized for sub-2 V operation, and attempting to run TPS62000YZGR below this limit may result in intermittent shutdown, poor line regulation, or failure to start. Always maintain VIN ≥2 V for reliable TPS62000YZGR functionality.
What is the purpose of the FC pin on TPS62000YZGR, and how should it be decoupled?
The FC (Filter Capacitor) pin on TPS62000YZGR provides dedicated high-frequency bypassing for the internal bias circuitry and oscillator. It must be connected to a 0.1 µF ceramic capacitor placed as close as possible to the pin and to the VIN supply. This capacitor stabilizes internal references and prevents noise coupling into the control loop. Omitting or misplacing the FC capacitor on TPS62000YZGR can cause erratic switching, audible coil whine, or startup failures-especially under dynamic load transients.
Does TPS62000YZGR support 100% duty-cycle operation, and what is its practical benefit?
Yes-TPS62000YZGR supports 100% duty-cycle operation when input voltage approaches output voltage, turning the high-side P-channel MOSFET fully on. This reduces dropout to only the RDS(on) × ILOAD loss (typically <100 mV at 600 mA), enabling regulation even when VIN is within 100–200 mV of VOUT. This feature is essential for TPS62000YZGR applications like low-VOUT FPGA cores or battery-fueled sensors where every millivolt of input headroom matters for maximizing runtime.
