Product details
Overview
TPS62616YFDT 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 TPS62616YFDT datasheet, TPS62616YFDT pinout, TPS62616YFDT application, or TPS62616YFDT 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 sub-0.4-mm solution profile requiring only three surface-mount components.
Technical Context
The TPS62616YFDT employs a frequency-locked ring-oscillating modulator architecture-eliminating traditional compensation loops-to achieve instantaneous load/line transient response and inherent stability across ceramic inductor/capacitor variations. It operates at regulated 6 MHz 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) or forced PWM (MODE = HIGH) for low-noise applications; EN enables shutdown with 0.2–1 µA leakage; FB senses output via internal 480-kΩ divider; and integrated active power-down discharges VOUT through a 15-Ω internal resistor.
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 voltage for RF ICs and baseband processors. |
| Max Output Current | 350 mA continuous - supports dual-core application processors or multi-radio SoCs in space-constrained handhelds. |
| Switching Frequency | Regulated 6 MHz (5.4–6.6 MHz) - enables use of 0603-size 0.47 µH inductors and 0402 ceramic capacitors for <10 mm² total solution size. |
| Quiescent Current | 31 µA typical in PFM mode - extends battery runtime in standby states without sacrificing transient response. |
| 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 coupling from noisy system rails into sensitive analog/RF blocks. |
| Startup Time | 96 ms from EN assertion - meets fast-boot requirements in mobile UI subsystems while limiting inrush current. |
Pinout & Package
TPS62616YFDT uses a 6-pin NanoFree™ chip-scale package (CSP-6, 0.4 mm max height, 0.8 mm × 0.8 mm footprint) with bottom-side solder bumps. Pin assignment follows standard top-view layout: A1=MODE, A2=VIN, B1=SW, B2=EN, C1=FB, C2=GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FB (C1) | Feedback sense input | Connects directly to VOUT; internal 480-kΩ divider sets regulation point - no external resistors required for fixed-output variants. |
| VIN (A2) | Power supply input | Accepts 2.3–5.5 V; supplies bias and switch driver - requires 4.7 µF ceramic input capacitor (0402) for stability. |
| SW (B1) | Switch node | Drain connection of internal P/N-MOSFET pair - routes to inductor; requires careful layout to minimize EMI and ringing. |
| MODE (A1) | Operating mode control | Pull LOW for auto PFM/PWM; pull HIGH for forced PWM - enables noise-sensitive applications without external circuitry. |
| EN (B2) | Enable input | Active-high logic; must be terminated - drives device into 0.2–1 µA shutdown state when grounded. |
| GND (C2) | Power ground | Primary return path for power and control circuits - requires low-inductance connection to PCB ground plane. |
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 life across usage states. |
| Integrated soft-start | 100-ms controlled ramp-up limits inrush current - prevents brownout during cold start on weak batteries or high-impedance sources. |
| Active output discharge | 15-Ω internal discharge path - clears VOUT within milliseconds after shutdown, preventing back-powering of downstream circuitry. |
| Ultra-low profile solution | Total height < 0.4 mm with 0603 inductor and 0402 capacitors - enables integration beneath displays or in stacked PCB assemblies. |
| High PSRR & transient response | >50 dB PSRR (1–10 kHz) and sub-10 µs load-step recovery - sustains clean supply for RF transceivers and ADCs during burst transmission. |

FAQ
What is the exact output voltage of the TPS62616YFDT?
The TPS62616YFDT delivers a factory-trimmed fixed output voltage of 2.15 V with ±2% total DC accuracy across input voltage (2.3–5.5 V), load current (0–350 mA), and temperature (–40°C to +85°C). This precision eliminates the need for external feedback resistors and ensures reliable operation in noise-sensitive RF and analog circuits where voltage tolerance directly impacts signal integrity.
Does the TPS62616YFDT require external feedback resistors?
No, the TPS62616YFDT does not require external feedback resistors. It integrates an internal 480-kΩ resistor divider optimized for its fixed 2.15 V output. The FB pin connects directly to the output node, simplifying design, reducing BOM count, and minimizing layout sensitivity - a key advantage over adjustable buck regulators that demand precise resistor matching and routing.
How does the MODE pin affect TPS62616YFDT operation?
The MODE pin on the TPS62616YFDT selects between two operating modes: pulling MODE LOW enables automatic PFM/PWM switching for maximum light-load efficiency, while pulling MODE HIGH forces continuous PWM operation for predictable 6-MHz switching and easier EMI filtering. Both modes retain full 350-mA capability and identical thermal performance - the choice depends solely on system noise requirements.
What is the startup behavior of the TPS62616YFDT?
The TPS62616YFDT features an internal soft-start circuit that ramps output voltage over ~100 ms after EN is asserted, limiting inrush current to protect weak batteries or high-impedance sources. If output fails to reach target within this window (e.g., under heavy load), it transitions to current-limited soft-start for an additional 100 ms before reaching full operation - ensuring robust startup across all conditions without external components.
Can the TPS62616YFDT safely discharge its output capacitor?
Yes, the TPS62616YFDT includes integrated active output discharge via a 15-Ω internal resistor. When EN is pulled low, this path rapidly discharges the VOUT capacitor - preventing back-powering of downstream circuitry, eliminating residual voltage hazards during hot-swap events, and ensuring clean power sequencing in multi-rail systems. Discharge time depends on output capacitance but typically completes within milliseconds.
