Product details
Overview
TPS62623YFFT from Texas Instruments is a 600-mA, 6-MHz synchronous step-down DC/DC converter in a 6-pin NanoFree™ WCSP package, optimized for Li-ion–powered portable devices. It delivers fixed 1.225 V output with ±2% DC accuracy, 31 μA quiescent current in PFM mode, and supports input range 2.3 V to 5.5 V - enabling use in smartphone core logic rails.
For engineers reviewing the TPS62623YFFT datasheet, TPS62623YFFT pinout, TPS62623YFFT application, or TPS62623YFFT equivalent, key selection considerations include its automatic PFM/PWM mode switching, sub-1-mm profile, 120-μs startup time, integrated soft-start, and thermal shutdown protection - all critical for space-constrained, battery-sensitive designs.
Technical Context
The TPS62623YFFT employs a frequency-locked ring-oscillating modulator architecture with no traditional compensated feedback loop, enabling instantaneous transient response and inherent stability across L/COUT variations. Its non-linear control maintains regulated 6 MHz switching under moderate-to-heavy loads while transitioning seamlessly to discontinuous-conduction-mode (DCM) PFM at light loads.
It integrates complementary P-channel and N-channel MOSFETs with RDS(on) of 640 mΩ (P-MOS) and 200 mΩ (N-MOS) at 2.5 V GS, plus undervoltage lockout (2.05 V threshold), active current limiting (975–1200 mA), and thermal shutdown (140°C trip, 10°C hysteresis) - all operating across –40°C to 85°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.3 V to 5.5 V - supports full Li-ion battery discharge curve without external regulation. |
| Output Voltage | Fixed 1.225 V ±2% - precision rail for low-voltage digital cores (e.g., ARM Cortex-M3/M4 I/O or memory interfaces). |
| Max Output Current | 600 mA - sufficient for RF transceivers, sensor hubs, or display drivers in handheld devices. |
| Switching Frequency | 6 MHz (±10%) - enables use of 0.47 μH chip inductors and 4.7 μF ceramic capacitors, minimizing solution size & EMI. |
| Quiescent Current | 31 μA (typical, PFM mode) - extends battery life during standby/sleep states in always-on subsystems. |
| Efficiency | 90% at 6 MHz, 1.8 V out / 3.6 V in / 600 mA - high conversion efficiency preserves thermal headroom in sealed enclosures. |
| Startup Time | 120 μs - fast power-up meets sequencing requirements for multi-rail SoCs with tight timing margins. |
Pinout & Package
TPS62623YFFT uses a 6-pin DSBGA (WCSP) package with 1.30 mm × 0.96 mm body size and 0.4-mm pitch. The NanoFree™ construction eliminates bond wires and substrate, achieving <1-mm height and minimal PCB footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Power input | Accepts 2.3–5.5 V supply; connects directly to battery or PMIC output; requires local 2.2-μF ceramic decoupling. |
| SW | Switch node | Drain connection of internal P-MOS/N-MOS; drives external 0.47-μH inductor; high dv/dt node requiring tight layout. |
| FB | Feedback sense | High-impedance (480 kΩ) input tied directly to VOUT; sets regulation point via internal 1.225-V reference. |
| MODE | Mode control | Pull to GND for auto PFM/PWM; pull to VIN for forced PWM - enables noise-sensitive operation without efficiency penalty at load. |
| EN | Enable input | Active-high logic; 1.0 V VIH threshold; pulls device into <0.25 μA shutdown when grounded; must not float. |
| GND | Ground reference | Power and signal return; requires low-inductance connection to thermal pad (exposed die attach area on bottom). |
Key Features
| Feature | Design Value |
|---|---|
| Automatic PFM/PWM mode switching | Maintains >85% efficiency from 10 μA to 600 mA load without external control - ideal for burst-mode processors. |
| Integrated soft-start | 120-μs controlled ramp limits inrush current and prevents input voltage droop on weak battery sources. |
| Low-ripple PFM mode | Delivers <24 mVPP ripple at 1 mA load - suitable for analog sensors and RF bias rails where switching noise must be minimized. |
| Thermal & overload protection | Shuts down at 140°C junction temperature and limits peak current to 975–1200 mA - prevents damage during short-circuit or overtemperature events. |
| Ultra-small solution size | Total PCB area <12 mm² with only three external components (inductor + two MLCCs) - fits behind camera modules or under displays. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62621YFFT | Fixed 1.8 V output; same 6-MHz operation, 31 μA IQ, and WCSP package. | Targets higher-voltage digital rails (e.g., SDIO, USB PHY); not suitable for 1.2-V core logic. | Select when system requires 1.8 V instead of 1.225 V - identical layout and BOM except FB network (not needed). |
| TPS62086YFFR | Adjustable output (0.8–5.5 V); 2-A capability; 2.5-MHz switching; QFN-11 package. | Designed for higher-current, multi-rail PMIC subsystems; larger footprint and higher IQ (15 μA in PFM, but no 31-μA ultra-low mode). | Choose for scalable designs needing programmability or >600 mA - requires new layout and thermal validation. |
Compared with TPS62621YFFT, TPS62623YFFT provides lower output voltage for advanced-node processors but shares identical transient performance and package compatibility; versus TPS62086YFFR, it trades current headroom and adjustability for ultra-low IQ and minimal footprint - making it optimal for single-rail, space-limited battery apps.

FAQ
What is the output voltage tolerance of the TPS62623YFFT over temperature and line/load conditions?
The TPS62623YFFT guarantees ±2% total DC voltage accuracy across –40°C to 85°C ambient, 2.3 V to 5.5 V input, and 0 mA to 600 mA load. This includes initial tolerance, line regulation (0.13%/V), and load regulation (–0.0003%/mA). Measured output remains within 1.200 V to 1.250 V under all specified conditions - critical for reliable operation of 1.2-V nominal logic circuits.
Does the TPS62623YFFT support output capacitor discharge functionality?
No, the TPS62623YFFT does not include active output capacitor discharge. That feature is exclusive to the TPS62624YFFT variant, which integrates a 15-Ω internal discharge resistor. The TPS62623YFFT leaves the output floating upon shutdown - requiring external circuitry if rapid VOUT decay is needed for system-level sequencing.
What is the recommended inductor value for optimal performance with the TPS62623YFFT?
Texas Instruments specifies 0.47 μH as the optimized inductor value for the TPS62623YFFT, paired with a 4.7-μF output capacitor. This combination achieves stable operation, minimal output ripple, and best-in-class transient response. Inductors from Murata (LQM21PNR47MC0), TDK (HSLI-201210AG-R47), or Taiyo Yuden (NM2012NR82) are validated - all rated for ≥600 mA saturation current and low DCR (<150 mΩ).
Can the TPS62623YFFT operate with input voltage below 2.3 V?
No - the TPS62623YFFT has an absolute minimum input voltage of 2.3 V per recommended operating conditions, and its undervoltage lockout (UVLO) disables operation below 2.05 V (typical). Attempting to operate below 2.3 V risks unstable regulation, increased ripple, or failure to start. For sub-2.3 V inputs, consider TI's TPS6274x series or alternative architectures.
How does the MODE pin affect efficiency and noise performance of the TPS62623YFFT?
When MODE is pulled low, the TPS62623YFFT automatically switches between PWM (heavy load) and PFM (light load), maximizing efficiency across the full 10 μA–600 mA range - achieving 90% at full load and >85% at 100 μA. When MODE is pulled high, it forces fixed-frequency PWM operation, eliminating PFM frequency variation and simplifying EMI filtering, but reduces light-load efficiency by ~15–20% due to constant switching losses.
