Product details
Overview
TPS62616YFDR from Texas Instruments is a 350-mA, 6-MHz synchronous step-down DC-DC converter in a 6-pin NanoFree™ CSP package (0.4 mm max height), delivering fixed 2.15 V output with ±2% total DC voltage accuracy, 90% peak efficiency, and 31 µA quiescent current - optimized for Li-ion-powered portable devices such as smartphones and Bluetooth modules.
For engineers reviewing the TPS62616YFDR datasheet, TPS62616YFDR pinout, TPS62616YFDR application, or TPS62616YFDR equivalent, key selection considerations include its automatic PFM/PWM mode switching, 2.3 V to 5.5 V input range, integrated soft-start (100-ms startup), and ultra-thin chip-scale packaging requiring only three surface-mount components.
Technical Context
The TPS62616YFDR employs a frequency-locked ring-oscillating modulator architecture-eliminating traditional compensation loops-to achieve instantaneous transient response and inherent stability across varied inductor and capacitor values. It maintains regulated 6 MHz switching in PWM mode and transitions to discontinuous-conduction-mode (DCM) PFM at light loads.
Its MODE pin selects between auto PFM/PWM operation (MODE = LOW) and forced fixed-frequency PWM (MODE = HIGH) for low-noise applications. Internal P- and N-channel MOSFETs feature rDS(on) of 350 mΩ and 200 mΩ respectively at VGS = 2.5 V, enabling high efficiency up to 350 mA while supporting ultralow-profile external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.15 V with ±2% total DC accuracy over line/load/temperature - ensures stable core or I/O rail without external feedback resistors. |
| Max Output Current | 350 mA continuous - supports RF transceivers, sensor hubs, and low-power microcontrollers in space-constrained designs. |
| Switching Frequency | Regulated 6 MHz (5.4–6.6 MHz range) - enables use of sub-1-µH inductors and 0402 ceramic capacitors for <10 mm² total solution size. |
| Quiescent Current | 31 µA in PFM mode - extends battery life in standby or sleep states of portable electronics. |
| Input Voltage Range | 2.3 V to 5.5 V - compatible with single-cell Li-ion (2.9–4.2 V) including extended discharge down to 2.3 V. |
| PSRR | >50 dB from 1 kHz to 10 kHz - suppresses noise from noisy battery or shared power rails in RF-sensitive applications. |
| Startup Time | 96 ms - controlled by internal soft-start to limit inrush current and prevent input voltage droop on weak sources. |
Pinout & Package
Package: 6-pin NanoFree™ Chip Scale Package (CSP-YFD), 0.4 mm maximum height, 0.8 mm × 0.8 mm footprint, bottom-side ball layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FB (C1) | Feedback sense input | Connected directly to VOUT; sets regulation point via internal resistor divider - no external resistors required for fixed-output variants like TPS62616YFDR. |
| VIN (A2) | Power input | Supplies internal bias and switch driver; accepts 2.3–5.5 V - must be decoupled with ≥4.7 µF ceramic capacitor per datasheet. |
| SW (B1) | Switch node | Drain connection of internal P- and N-MOSFETs; drives external inductor - requires careful PCB layout to minimize EMI and ringing. |
| MODE (A1) | Mode control input | Pull LOW for auto PFM/PWM; pull HIGH for forced PWM - enables dynamic noise-performance trade-off during system operation. |
| EN (B2) | Enable input | Active-HIGH logic; ties to system power rail or GPIO - floating EN is prohibited; shutdown draws ≤1 µA. |
| GND (C2) | Ground reference | Primary return path for power and control circuits; must be connected to low-impedance ground plane beneath CSP thermal pad. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic PFM/PWM mode switching | Maintains >85% efficiency from 10 µA to 350 mA load - eliminates manual mode control and optimizes battery runtime across usage states. |
| Integrated active output discharge | 15 Ω internal discharge resistor - safely drains VOUT capacitor during shutdown, preventing residual voltage from interfering with downstream logic sequencing. |
| Ultra-low profile solution | Total height <0.4 mm with 0603 inductor and two 0402 capacitors - meets mechanical constraints of slim smartphones and wearables. |
| Best-in-class transient response | Sub-10 µs recovery from 30–150 mA load steps - preserves regulation during burst-mode RF transmission or sensor sampling. |
| Internal soft-start | 100-ms ramp-up with current limiting - prevents input collapse on coin-cell or aging Li-ion batteries during cold start. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62615YFDR | Fixed 1.2 V output; identical package, pinout, and electrical specs except output voltage and FB divider ratio. | Suitable for low-voltage logic rails (e.g., MCU cores), not 2.15 V I/O domains. | Select when system requires 1.2 V instead of 2.15 V; no layout change needed. |
| TPS62619YFDR | Fixed 1.8 V output; same CSP-6 package, timing, and efficiency profile; differs only in output voltage setting. | Used in 1.8 V memory interfaces and digital basebands where 2.15 V is incompatible. | Choose for 1.8 V applications; shares identical footprint, thermal behavior, and external component requirements. |
Compared with TPS62615YFDR and TPS62619YFDR, the TPS62616YFDR provides the precise 2.15 V output required for certain RF front-end biasing and analog sensor interfaces - a value not covered by other members of the family, making it irreplaceable in those specific voltage-domain designs.

FAQ
What is the exact output voltage of the TPS62616YFDR?
The TPS62616YFDR delivers a factory-trimmed fixed output voltage of 2.15 V with ±2% total DC accuracy across input voltage (2.3 V–5.5 V), load (0–350 mA), and temperature (–40°C to +85°C). This value is set internally and does not require external feedback resistors - confirmed in the Ordering Information table and Electrical Characteristics section of the SLVS936A datasheet.
Does the TPS62616YFDR require external compensation components?
No, the TPS62616YFDR does not require external compensation components. Its frequency-locked ring-oscillating modulator architecture eliminates the need for loop compensation networks. Stability is inherent across recommended inductor (0.47 µH) and output capacitor (4.7 µF) ranges - verified in the DETAILED DESCRIPTION and PARAMETER MEASUREMENT INFORMATION sections.
Can the TPS62616YFDR operate from a 2.3 V input supply?
Yes, the TPS62616YFDR operates down to 2.3 V input, as specified in the Absolute Maximum Ratings and Electrical Characteristics tables. Its undervoltage lockout (UVLO) threshold is 2.05 V (typ), and full functionality is guaranteed from 2.1 V. At 2.3 V input, it sustains 350 mA output with >82% efficiency - validated in Figure 6 (Efficiency vs Input Voltage) and Table 1.
What is the thermal performance of the TPS62616YFDR in its YFD-6 package?
The TPS62616YFDR in the YFD-6 package has a junction-to-ambient thermal resistance (θJA) of 125°C/W on a 4-layer JEDEC-standard board. With 800 mW maximum power dissipation at TA ≤25°C and 8 mW/°C derating above 25°C, it supports continuous 350 mA operation at ambient temperatures up to 85°C - per Dissipation Ratings table and Thermal Shutdown specification (140°C trip, 10°C hysteresis).
How does the MODE pin affect efficiency and noise in the TPS62616YFDR?
When MODE = LOW, the TPS62616YFDR automatically switches between high-efficiency PFM (31 µA IQ) at light loads and fixed-frequency PWM at heavy loads. When MODE = HIGH, it forces continuous PWM operation - reducing output voltage ripple and EMI at the cost of higher light-load quiescent current (~6.6 µA). This trade-off is documented in Figures 21–24 and the MODE SELECTION section.
