Product details
Overview
TPS62690YFFR from Texas Instruments is a 500-mA, 4-MHz synchronous step-down DC-DC converter in a 6-pin NanoFree™ CSP package, delivering 2.85 V output with ±2% DC accuracy and 95% peak efficiency at light-to-heavy loads. It operates from 3.15 V to 4.8 V input, features PFM/PWM auto-mode switching, 19 µA quiescent current, and integrated soft-start for battery-powered mobile phones and portable media devices.
For engineers reviewing the TPS62690YFFR datasheet, TPS62690YFFR pinout, TPS62690YFFR application, or TPS62690YFFR equivalent, key selection criteria include its sub-1-mm profile, 250-µs startup time, 4-MHz fixed-frequency PWM capability (via MODE pin), low-noise PFM operation, and compatibility with 0402/0603 MLCCs and 2012 chip inductors.
Technical Context
The TPS62690YFFR employs a frequency-locked ring-oscillating modulator architecture-eliminating traditional compensation loops-to achieve instantaneous load/line transient response and inherent stability across wide ranges of inductor (0.5–1.8 µH) and output capacitance (1–10 µF). Its non-linear control enables seamless PFM-to-PWM mode transition without output voltage overshoot.
It integrates dual MOSFET power switches (P-channel rDS(on) = 160 mΩ typ at 3.6 V; N-channel rDS(on) = 110 mΩ typ), active power-down sequencing with 100 Ω discharge resistor, and undervoltage lockout (2.1 V threshold). MODE pin selection determines whether operation defaults to auto PFM/PWM or forced PWM for noise-sensitive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.85 V with ±2% total DC accuracy over line/load/temperature - ensures stable core supply for low-voltage SoCs without external feedback resistors. |
| Max Output Current | 500 mA peak - supports moderate-power RF transceivers, audio codecs, and display drivers in single-cell Li-ion systems. |
| Switching Frequency | Regulated 4 MHz (3.6–4.4 MHz range) - enables use of ultra-small 1–2 µH inductors and minimizes EMI filter footprint. |
| Quiescent Current | 19 µA typical in PFM mode - extends battery life in standby/sleep states of smartphones and wearables. |
| Input Voltage Range | 3.15 V to 4.8 V - matches nominal and depleted voltage range of single-cell Li-ion batteries (3.0–4.2 V). |
| Startup Time | 250 µs from EN assertion to regulated VOUT - meets fast wake-up timing requirements in always-on sensor subsystems. |
| Thermal Resistance | θJA = 133.2 °C/W (YFF package) - defines maximum ambient temperature derating for continuous 500-mA operation on standard PCBs. |
Pinout & Package
Package: 6-pin NanoFree™ (CSP-YFF), 1.0 mm × 1.0 mm × 0.55 mm, bottom-soldered die-attach, no leadframe - enables ultra-compact, low-profile power solutions (<12 mm² total board area).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FB (C1) | Feedback sense input | Direct connection to VOUT; internal 480-kΩ divider sets 2.85 V - no external resistors required. |
| VIN (A2) | Input power supply | Accepts 3.15–4.8 V; powers internal bias circuitry and high-side switch - requires local 4.7-µF ceramic bypass. |
| SW (B1) | Switch node | Drain connection of internal P/N-MOSFETs - routes to external inductor; critical for EMI layout and thermal path. |
| MODE (A1) | Operating mode control | Pull to GND for auto PFM/PWM; pull to VIN for forced PWM - enables dynamic noise/efficiency trade-off. |
| EN (B2) | Enable input | Active-high logic; <0.4 V disables device (0.2 µA shutdown current); must not float - ties to system PMIC rail. |
| GND (C2) | Power ground | Primary return path for power and control circuits - requires low-impedance thermal pad connection to PCB ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| 95% peak efficiency at 4 MHz | Enables >2× longer runtime vs. LDOs in 3.6-V → 2.85-V conversion, while maintaining small solution size. |
| Low-ripple PFM mode | 25 mVPP output ripple at 1 mA with 10-µF output cap - preserves signal integrity in analog/audio sections. |
| Integrated soft-start (250 µs) | Prevents inrush current-induced input droop on weak sources like coin-cell or aging Li-ion batteries. |
| Active output discharge (100 Ω) | Ensures rapid VOUT collapse during shutdown - prevents back-powering of downstream logic or leakage paths. |
| ≥40 dB PSRR (1–10 kHz) | Rejects noise from noisy digital rails or shared battery sources - eliminates need for post-regulation LDOs. |
| 100% duty-cycle low-dropout | Maintains regulation down to VIN ≈ VOUT + IOUT×rDS(on) - extracts maximum energy from dying battery cells. |

FAQ
What is the recommended input capacitor for TPS62690YFFR?
The TPS62690YFFR datasheet specifies a 4.7-µF, 6.3-V, X5R, 0402 ceramic capacitor (e.g., Murata GRM155R60J475M) as the minimum input capacitance. This value ensures stable operation across the 3.15–4.8 V input range and suppresses high-frequency switching noise injected back into the source rail. Larger values improve hold-up time but are not required for basic functionality.
Does TPS62690YFFR support forced PWM mode?
Yes, TPS62690YFFR supports forced PWM mode via the MODE pin: pulling MODE high (to VIN) disables automatic PFM entry and locks the converter into regulated 4-MHz PWM operation regardless of load current. This reduces output voltage ripple harmonics and simplifies EMI filtering in noise-sensitive analog sections, though at the cost of higher light-load quiescent current.
What is the thermal performance of TPS62690YFFR in its YFF package?
TPS62690YFFR in the YFF CSP package has a junction-to-ambient thermal resistance (θJA) of 133.2 °C/W under standard JEDEC conditions. With 500-mA output current and 3.6-V input, typical power dissipation is ~120 mW, resulting in ~16 °C junction-to-ambient rise - well within the 125 °C max operating junction temperature. PCB copper area under the thermal pad significantly improves this rating.
Can TPS62690YFFR replace an LDO in a battery-powered design?
Yes, TPS62690YFFR is explicitly positioned as an LDO replacement: it delivers 2.85 V at up to 500 mA with 95% efficiency (vs. ~50–70% for LDOs), 19 µA quiescent current in PFM mode, and ≥40 dB PSRR. Its 100% duty-cycle capability maintains regulation down to near-battery-dead voltage, extending runtime beyond what linear regulators can achieve.
What protection features does TPS62690YFFR include?
TPS62690YFFR integrates current overload protection (830 mA typical P-MOS limit), thermal shutdown (140 °C trip, 10 °C hysteresis), undervoltage lockout (2.1 V), and active output discharge (100 Ω internal resistor). These features prevent damage during short-circuit events, overtemperature conditions, brownout, and ensure safe power-down sequencing without external components.
