Product details
Overview
LMR22007YYZFT from Texas Instruments is a synchronous step-down DC-DC converter delivering up to 750 mA output current with adjustable input current limit (150–600 mA), 2.7V–20V input range, and 0.9V–5.5V adjustable output voltage. It features 2.1 MHz fixed switching frequency, 18 µA quiescent current, and integrated soft-start for powering low-power embedded interfaces in space-constrained applications.
For engineers reviewing the LMR22007YYZFT datasheet, LMR22007YYZFT pinout, LMR22007YYZFT application, or LMR22007YYZFT equivalent, this device is selected for POL supplies requiring ultra-low IQ, input current limiting, and compact WCSP packaging in battery-powered mobile and industrial edge devices.
Technical Context
The LMR22007YYZFT implements DCS-Control™ topology-combining voltage-mode stability with hysteretic transient response-enabling seamless transition between PWM and power-save modes without output disturbance. Its internal compensation eliminates external loop components, while adaptive on-time control maintains regulation across wide VIN/VOUT combinations.
It integrates NMOS high-side (0.21 Ω typical RDS(on)) and low-side (0.144 Ω typical RDS(on)) switches, thermal shutdown (155°C trip), UVLO (2.6 V rising threshold), and open-drain power-good flag with 0.855 V rising threshold referenced to FB. Input current limiting is resistor-adjustable via ILIM pin with 200 kΩ setting 600 mA typical limit at 12 VIN.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7 V to 20 V - supports single/dual Li-ion, 5 V/12 V rails, and transient tolerance up to 24 V. |
| Output Current | 750 mA continuous - sufficient for core logic, I/O interfaces, and sensor subsystems in portable electronics. |
| Switching Frequency | 2.1 MHz typical - enables use of small 2.2 µH inductors and 22 µF ceramic output capacitors for <26 mm² solution size. |
| Quiescent Current | 18 µA typical - extends battery life in always-on standby modes without sacrificing startup speed. |
| Feedback Reference | 0.9 V ±1% - sets output voltage via resistor divider; enables precise 3.3 V, 5 V, or custom outputs with <±1% ripple at full load. |
| Input Current Limit | Adjustable 150–600 mA via ILIM pin - protects upstream sources (e.g., USB ports, battery fuel gauges) without external sense resistors. |
| Thermal Shutdown | 155°C junction trip with 25°C hysteresis - ensures safe operation under sustained overload or poor PCB thermal design. |
Pinout & Package
LMR22007YYZFT uses a 9-bump Wafer Chip Scale Package (WCSP) with 0.5 mm pitch and 300 µm bump height. The package is bottom-terminal, requiring solder paste stencil optimization and board-level reflow profiling per TI SNOA859.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | AGND | Analog ground reference for internal error amplifier and feedback circuitry; must be connected to quiet ground plane separate from PGND. |
| A2 | ILIM | Resistor-adjustable input current limit set point; connects to GND via 200 kΩ to achieve ~600 mA limit at 12 VIN. |
| A3 | EN | Enable control with 0.9 V rising threshold; self-starts when tied to VIN via ≤3 kΩ; pulls down internally during soft-start. |
| B1 | FB | Feedback node for output voltage regulation; requires resistor divider to scale VOUT to 0.9 V reference. |
| B2 | PG | Open-drain power-good flag; floats when VFB > 0.855 V, sinks 5 mA when VFB < 0.812 V - used for rail sequencing. |
| B3 | VIN | Main input supply; rated for 24 V absolute max; requires 10 µF X7R ceramic capacitor placed adjacent to PGND. |
| C1 | VOUT | Regulated output node; connects directly to 22 µF output capacitor and load; no external catch diode needed. |
| C2 | SW | Switch node connecting to external 2.2 µH inductor; experiences fast dV/dt edges; requires tight layout to minimize EMI. |
| C3 | PGND | Power ground return for high-current switch paths; must be low-inductance connection to input/output capacitors. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control™ architecture | Enables <10 µs load transient response and stable operation with low-ESR ceramic capacitors without external compensation. |
| Adjustable input current limit | Set from 150 mA to 600 mA using single resistor on ILIM pin - avoids overloading USB-C or battery protection ICs. |
| Ultra-low quiescent current | 18 µA typical in active mode - reduces standby power loss by >5× vs. comparable 1 A buck converters. |
| Integrated soft-start | 3.3 ms internal ramp - prevents inrush current into pre-biased loads and eliminates need for external timing components. |
| Power-good flag with hysteresis | 0.855 V rise / 0.812 V fall thresholds on FB - provides clean, glitch-free sequencing signal for multi-rail systems. |
| Thermal and UVLO protection | 155°C shutdown with 25°C hysteresis + 2.6 V UVLO with 269 mV hysteresis - ensures robust operation under fault conditions. |

FAQ
What is the recommended inductor value for LMR22007YYZFT in a 3.3 V output application?
The recommended inductor value for LMR22007YYZFT in a 3.3 V output application is 2.2 µH, as validated in TI's reference design and electrical characteristics testing. This value balances stability, transient response, and efficiency across the full 2.7 V–20 V input range. Using 2.2 µH with 22 µF X7R output capacitance achieves <1% output ripple at full load and ensures seamless entry into power-save mode below ~150 mA load current. Inductor saturation current must exceed 1.3 A to accommodate peak currents.
How does the input current limit function on LMR22007YYZFT, and what resistor value sets 600 mA?
The input current limit on LMR22007YYZFT is set by connecting a resistor from the ILIM pin (A2) to AGND. A 200 kΩ resistor configures a typical 600 mA input current limit at 12 VIN, per the device's transfer function and characterization curves. The limit adjusts inversely with resistor value: lower resistance increases the limit, higher resistance decreases it. This feature protects upstream sources like USB ports or battery fuel gauges without requiring external current-sense circuitry or MOSFETs.
Does LMR22007YYZFT require external compensation components?
No, LMR22007YYZFT does not require external compensation components. It features fully internal compensation optimized for ceramic output capacitors ranging from 10 µF to 200 µF. This eliminates the need for external RC networks, simplifies layout, reduces BOM count, and accelerates design cycle time. The DCS-Control™ architecture inherently stabilizes the loop across temperature, input voltage, and load variations without user tuning.
What is the purpose of the PG (power good) pin on LMR22007YYZFT, and how should it be interfaced?
The PG pin on LMR22007YYZFT is an open-drain output that signals valid regulation: it floats when FB voltage exceeds 0.855 V and pulls low when FB falls below 0.812 V. To interface, connect a pull-up resistor (typically 100 kΩ) from PG to the desired logic voltage (≤20 V). This signal enables safe power-rail sequencing in multi-supply systems, such as asserting reset to an MCU only after the 3.3 V rail is stable. No external driver or level shifter is needed.
Can LMR22007YYZFT operate with a 24 V input transient, and what protection mechanisms apply?
Yes, LMR22007YYZFT is rated for 24 V absolute maximum input voltage on VIN, SW, and PG pins, allowing safe operation during 24 V transients. Protection mechanisms include input under-voltage lockout (UVLO) with 2.6 V rising threshold and 269 mV hysteresis, thermal shutdown at 155°C, and internal overvoltage protection that disables the high-side FET if FB exceeds 1.017 V (13% above 0.9 V reference). These features ensure robustness in automotive and industrial environments with noisy or unstable inputs.
