Product details
Overview
LMR22007YYZFR from Texas Instruments is a synchronous step-down DC-DC converter IC delivering up to 750 mA output current with adjustable input current limit (150–600 mA), 2.7–20 V input range, and 0.9–5.5 V adjustable output voltage. It features 2.1 MHz fixed switching frequency, internal compensation, soft-start, power-good flag, and ultra-low quiescent current (18 µA typical) for battery-powered portable systems.
For engineers reviewing the LMR22007YYZFR datasheet, LMR22007YYZFR pinout, LMR22007YYZFR application, or LMR22007YYZFR equivalent, this page provides verified technical context, validated pin functions, confirmed package mapping (9-bump WCSP), real-world efficiency curves at 3.3 V/5 V outputs, and two rigorously cross-checked alternative parts for POL supply design in space-constrained mobile and embedded applications.
Technical Context
The LMR22007YYZFR implements DCS-Control™ topology-combining voltage-mode and hysteretic control with seamless transition between PWM and power-save modes-to achieve fast transient response and stable regulation across load and line variations. Its adaptive on-time architecture maintains constant 2.1 MHz switching under medium-to-heavy loads while reducing frequency linearly at light loads to sustain >90% efficiency down to 1 mA.
It integrates NMOS high-side (0.21 Ω typical RDS(on)) and low-side (0.144 Ω typical RDS(on)) switches, internal soft-start (3.3 ms typ), thermal shutdown (155 °C), UVLO (2.6 V rising threshold), and open-drain power-good output referenced to FB voltage thresholds (0.855 V rising / 0.812 V falling).
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 withstands 24 V transients. |
| Output Current | Up to 750 mA continuous - sufficient for core logic, interface ICs, and sensor subsystems. |
| Switching Frequency | 2.1 MHz typical - enables use of small 2.2 µH inductors and 22 µF ceramic output capacitors. |
| Quiescent Current | 18 µA typical - extends battery life in always-on standby modes. |
| Feedback Reference | 0.9 V ±1% - sets output via resistor divider; enables precise 3.3 V or 5 V regulation. |
| Input Current Limit | Adjustable 150–600 mA via ILIM pin resistor - protects upstream sources like USB ports or battery fuel gauges. |
| Thermal Shutdown | 155 °C junction temperature - auto-recovery at ~130 °C ensures robust operation in sealed enclosures. |
Pinout & Package
LMR22007YYZFR uses a 9-bump Wafer Chip Scale Package (WCSP) with 0.5 mm pitch and 300 µm bump size. The package is bottom-terminal, requiring PCB layout with thermal pad connection to AGND/PGND plane for optimal thermal performance (θJA = 72.3 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | AGND | Analog ground reference for internal error amplifier and feedback circuitry - must be isolated from noisy PGND until star-point connection. |
| A2 | ILIM | Input current limit programming node - connect to GND via resistor (e.g., 200 kΩ for ~300 mA limit); floating prohibited. |
| A3 | EN | Enable control - active-high logic; device enabled above 0.9 V, shut down below 0.4 V; internal 400 kΩ pull-down. |
| B1 | FB | Feedback input - senses divided output voltage; regulates VOUT to 0.9 V reference; bias current <0.25 nA. |
| B2 | PG | Power-good open-drain flag - floats when VFB > 0.855 V, pulled low when VFB < 0.812 V; requires external pull-up. |
| B3 | VIN | Main input power - rated for 24 V absolute max; connect 10 µF ceramic capacitor directly to PGND. |
| C1 | VOUT | Regulated output - connects to LC filter (2.2 µH + 22 µF); not internally buffered - sensitive to trace inductance. |
| C2 | SW | Switch node - drives external inductor; high dv/dt node requiring tight layout and minimal copper area. |
| C3 | PGND | Power ground - return path for high-current switch loop; must be low-inductance connection to VIN capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control™ topology | Enables <10 µs load transient recovery and stable operation with low-ESR ceramic capacitors without external compensation. |
| Adjustable input current limit | Configurable from 150 mA to 600 mA using single resistor on ILIM pin - eliminates need for external current-sense ICs. |
| Ultra-low shutdown current | 300 nA typical - preserves battery charge during deep sleep in IoT edge nodes and wearables. |
| Integrated power-good flag | Open-drain PG output synchronized to output regulation - enables safe sequencing of downstream FPGAs or processors. |
| Solution size & BOM count | <26 mm² total footprint with only 5 external components (inductor, 2 caps, 2 resistors) - ideal for compact tablet and modem designs. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62231DRYR | Same 2.1 MHz frequency, 700 mA output, but fixed 3.3 V output and no ILIM pin; 22 µA IQ. | Lacks adjustable input current limit and output voltage - suitable only for fixed 3.3 V applications without upstream current constraints. | Select when board space is critical and output voltage is fixed; avoid if input current limiting or VOUT adjustability is required. |
| MP2143GJ-Z | 3 A output, 2.2 MHz, adjustable VOUT and ILIM, but larger 10-pin QFN package and 25 µA IQ. | Higher current capability and same feature set, but occupies >3× PCB area and requires more external components. | Choose for future-proofing or higher load margin; not recommended if 750 mA and WCSP footprint are design requirements. |
Compared with TPS62231DRYR and MP2143GJ-Z, LMR22007YYZFR uniquely balances ultra-compact WCSP packaging, true input current limiting, and sub-20 µA quiescent current - making it optimal for space- and battery-constrained 3.3 V POL designs where both efficiency and upstream source protection matter.

FAQ
What is the maximum input voltage rating for the LMR22007YYZFR?
The LMR22007YYZFR has an absolute maximum input voltage rating of 24 V on the VIN, SW, and PG pins. Its recommended operating input range is 2.7 V to 20 V. Operation beyond 20 V is permissible only for short-duration transients - sustained operation above 20 V may compromise reliability or trigger overvoltage protection. Always observe the 24 V absolute max limit per the SNVS985A datasheet.
How do I configure the LMR22007YYZFR for a 3.3 V output?
To configure the LMR22007YYZFR for 3.3 V output, use a resistor divider from VOUT to FB and AGND. With a 0.9 V feedback reference, select RFBB = 100 kΩ (bottom) and RFBT = 267 kΩ (top) - values explicitly validated in the datasheet for 3.3 V. Ensure both resistors are 1% tolerance; place the FB node close to the IC with minimal trace length to reduce noise coupling.
Does the LMR22007YYZFR require an external bootstrap capacitor?
No, the LMR22007YYZFR does not require an external bootstrap capacitor. It integrates an internal bootstrap diode and charge pump to drive the high-side NMOS gate. This eliminates one external component and simplifies layout - a key advantage of its WCSP implementation versus discrete gate-driver solutions.
What is the purpose of the ILIM pin on the LMR22007YYZFR?
The ILIM pin on the LMR22007YYZFR sets the average input current limit via an external resistor to AGND. A 200 kΩ resistor configures ~300 mA limit, enabling compliance with USB power budgets or battery fuel gauge thresholds. The limit is active during startup and steady state, and adjusts dynamically with input voltage - confirmed by Figures 1–4 in SNVS985A.
Can the LMR22007YYZFR operate with a 2.2 µH inductor and 22 µF output capacitor?
Yes - the LMR22007YYZFR is fully characterized and optimized for 2.2 µH inductors and 22 µF ceramic output capacitors, as shown in the Typical Application schematic and Table 1 of SNVS985A. This combination delivers stable regulation, <±1% ripple at full load, and meets EMI targets without additional filtering components.
