Product details
Overview
TPS62623YFFR 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, 90% peak efficiency at 6 MHz, and 31 μA quiescent current in PFM mode-enabling extended battery life in smartphones and Bluetooth modules.
For engineers reviewing the TPS62623YFFR datasheet, TPS62623YFFR pinout, TPS62623YFFR application, or TPS62623YFFR equivalent, key selection criteria include its regulated 6-MHz switching frequency, automatic PFM/PWM mode transition, 2.3 V to 5.5 V input range, integrated soft-start (120-μs startup), and WCSP thermal performance (RθJA = 130°C/W).
Technical Context
The TPS62623YFFR employs a frequency-locked ring-oscillating modulator architecture with no traditional compensated feedback loop-delivering instantaneous transient response and inherent stability across L/C variations. Its non-linear control enables best-in-class load/line regulation (0.13%/V line, –0.0003%/mA load) without external compensation.
It integrates dual MOSFET power switches (P-channel RDS(on) = 640 mΩ, N-channel RDS(on) = 200 mΩ at 2.5 V), undervoltage lockout (2.05 V threshold), thermal shutdown (140°C), and cycle-by-cycle current limiting (1.1 A nominal). MODE pin selects between auto PFM/PWM or forced PWM operation; EN enables soft-start and shutdown (0.2 μA ISD).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.225 V with ±2% total DC accuracy over temperature and line/load-ensures stable core voltage for low-power processors. |
| Max Output Current | 600 mA continuous-supports RF transceivers and sensor subsystems without derating in compact layouts. |
| Switching Frequency | Regulated 6 MHz (5.4–6.6 MHz range)-enables use of sub-1-μH inductors and 0402 ceramic capacitors for <12 mm² solution size. |
| Quiescent Current | 31 μA typical in PFM mode-extends standby time in always-on wearable sensors and IoT edge nodes. |
| Input Voltage Range | 2.3 V to 5.5 V-fully supports single-cell Li-ion (2.7–4.2 V) including discharge down to 2.3 V with UVLO margin. |
| Efficiency Peak | 90% at 6 MHz operation-minimizes thermal rise in thermally constrained mobile PCBs with no heatsink required. |
| Startup Time | 120 μs-meets fast-wake timing requirements for Bluetooth LE and GPS cold-start sequences. |
Pinout & Package
TPS62623YFFR uses a 6-pin DSBGA (NanoFree™ WCSP) package, 1.30 mm × 0.96 mm body size, 0.4-mm pitch, bottom-side solder balls. Thermal resistance: RθJA = 130°C/W, RθJB = 22°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| MODE (A1) | Mode selection input | Pull low for auto PFM/PWM; pull high for forced PWM-enables noise-sensitive RF coexistence without layout changes. |
| VIN (A2) | Power input | Accepts 2.3–5.5 V; internal UVLO prevents misoperation below 2.05 V-protects system during battery brownout. |
| SW (B1) | Switch node | Connects to external 0.47-μH inductor; internal P/N MOSFETs switch at 6 MHz-requires tight layout to minimize EMI. |
| EN (B2) | Enable control | Active-high; 120-μs soft-start limits inrush into 4.7-μF output cap-prevents input rail collapse on shared battery rails. |
| FB (C1) | Feedback sense | Direct connection to VOUT; internal 480-kΩ divider sets 1.225 V-no external resistors needed, reducing BOM count. |
| GND (C2) | Ground reference | Primary thermal and signal return path; must be solid copper under package per TI layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic PFM/PWM mode switching | Maintains >85% efficiency from 10 μA to 600 mA load-eliminates manual mode control in dynamic power states. |
| Low-ripple light-load PFM mode | 24 mVPP output ripple at 1 mA-preserves signal integrity in analog sensor front-ends without added filtering. |
| Integrated soft-start | 120-μs controlled ramp-prevents overshoot and avoids false triggers in downstream reset circuits. |
| Thermal shutdown with hysteresis | 140°C trip / 130°C recovery-protects silicon during sustained 600-mA operation in sealed enclosures. |
| Three external component requirement | Only one MLCC inductor + two ceramic caps needed-reduces footprint to <12 mm² and accelerates layout validation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62621YFFR | Fixed 1.8 V output; identical 6-MHz operation, PFM/PWM, package, and pinout | Targets 1.8-V I/O domains (e.g., SDIO, UART) rather than 1.225-V core logic | Select when system requires 1.8-V rail with same efficiency and footprint-no PCB change needed. |
| TPS62086RLTR | Adjustable 0.8–3.3 V output; 2.5-MHz switching; higher 1.2-A rating; 3-mm × 3-mm QFN | Suitable for higher-current, multi-rail systems requiring flexibility; larger thermal mass | Choose for designs needing programmable output or >600 mA-requires new layout and thermal validation. |
Compared with TPS62623YFFR, TPS62621YFFR offers identical performance at 1.8 V for I/O supply, while TPS62086RLTR trades compactness and ultra-low IQ for higher current and adjustability-making it appropriate only when 1.225 V is not required or load exceeds 600 mA.

FAQ
What is the exact output voltage tolerance of the TPS62623YFFR over temperature and load?
The TPS62623YFFR has ±2% total DC voltage accuracy across –40°C to 85°C ambient temperature, 2.3 V to 5.5 V input, and 0–600 mA load. This includes initial tolerance, line regulation (0.13%/V), and load regulation (–0.0003%/mA), verified per SLVS848D Section 7.5. The TPS62623YFFR maintains this spec without external feedback components due to its internal precision divider.
Does the TPS62623YFFR support forced PWM mode, and how is it enabled?
Yes, the TPS62623YFFR supports forced PWM mode via the MODE pin. Pulling MODE high (≥1.0 V) disables automatic PFM/PWM transition and locks the device into fixed 6-MHz PWM operation-even at light loads. This reduces output voltage ripple and simplifies EMI filtering for noise-sensitive RF sections, though quiescent current rises to 7.6 mA in that mode.
What is the recommended inductor value for the TPS62623YFFR, and why is 0.47 μH specified in the datasheet?
The TPS62623YFFR is internally compensated for optimal stability with 0.47 μH inductance and 4.7 μF output capacitance. While inductors from 0.3 μH to 1.3 μH are supported, 0.47 μH balances peak-to-peak ripple current, transient response, and efficiency. Murata LQM21PNR47MC0 is the validated part per TI's Table 2 and Figure 5 schematic.
How does the TPS62623YFFR handle short-circuit conditions, and what protection features are integrated?
The TPS62623YFFR integrates cycle-by-cycle P-channel MOSFET current limiting (1.1 A nominal), thermal shutdown (140°C), and undervoltage lockout (2.05 V). During short circuit, it reduces current limit to 550 mA once VOUT falls below 0.4 V, preventing latch-up. The TPS62623YFFR also disconnects internal feedback during shutdown and draws only 0.2 μA in EN = low state.
Is the TPS62623YFFR pin-compatible with other members of the TPS6262x family, and which variants share the same YFFR package?
Yes, all TPS6262x devices-including TPS62620, TPS62621, TPS62622, TPS62623, TPS62624, and TPS62625-use identical 6-pin DSBGA (YFF/YFD) packaging and pinout. The TPS62623YFFR shares mechanical and electrical compatibility with TPS62621YFFR and TPS62620YFFR, differing only in fixed output voltage (1.225 V) and absence of active discharge (unlike TPS62624).
