Product details
Overview
LM8801TME-2.9/NOPB from Texas Instruments is a high-precision, 6 MHz synchronous step-down DC-DC converter delivering up to 600 mA output current with ±1.5% DC output voltage accuracy at VOUT = 2.9 V, operating from 2.3 V to 5.5 V input, and featuring auto PFM/PWM mode switching for mobile power management.
For engineers reviewing the LM8801TME-2.9/NOPB datasheet, LM8801TME-2.9/NOPB pinout, LM8801TME-2.9/NOPB application, or LM8801TME-2.9/NOPB equivalent, key selection criteria include its 6 MHz fixed-frequency PWM operation, 27 µA quiescent current in PFM mode, 6-bump DSBGA package (1.065 × 1.265 mm), internal soft-start, and thermal shutdown protection - all critical for ultra-low-voltage portable system design.
Technical Context
The LM8801TME-2.9/NOPB implements voltage-mode control with input voltage feed-forward to achieve excellent line and load regulation across its 2.3 V–5.5 V input range. Its synchronous rectification uses an internal PFET/NFET pair with RDS(ON) of 220 mΩ (P) and 180 mΩ (N) at 3.6 V, enabling >90% efficiency at 6 MHz under medium-to-heavy loads.
In Auto mode (MODE = LOW), it dynamically transitions between PFM (for <50 mA loads, IQ = 27 µA typ.) and PWM (≥80 mA, fixed 6 MHz switching), maintaining tight output regulation while optimizing battery life. The FB pin senses output voltage with ±1.5% tolerance, and EN enables/disables the device with logic-level thresholds (VIL = 0.4 V, VIH = 1.2 V).
Key Specifications

Pinout & Package
LM8801TME-2.9/NOPB is housed in a 6-bump DSBGA package (package codes YFQ0006LCA/YQA0006LCA), optimized for minimal board area and high-density mobile layouts. Requires NSMD pads and precision reflow per TI Application Note AN-1112.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1: MODE | Mode selection control | LOW = Auto PFM/PWM switching; HIGH = forced PWM - enables dynamic efficiency optimization based on real-time load demand. |
| A2: VIN | Main power input | Accepts 2.3–5.5 V; requires local 2.2 µF ceramic capacitor to suppress high-frequency switching noise and supply peak currents. |
| B1: SW | Switching node | Connects internal PFET drain and NFET source; carries high di/dt current - must be routed short and away from sensitive traces. |
| B2: EN | Enable control | Logic-level input: <0.4 V = shutdown (0.08 µA ISHDN), >1.2 V = active - used for system-level power sequencing and battery-saving sleep modes. |
| C1: FB | Feedback input | Senses output voltage via resistive divider (not required for fixed-output variants like LM8801TME-2.9/NOPB); directly connected to output capacitor for stability. |
| C2: GND | Power ground | Common return for all internal circuits and external components - must be tied to low-impedance ground plane with multiple vias to minimize noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Auto PFM/PWM mode switching | Reduces quiescent current to 27 µA at light loads while maintaining fast transient response (<10 µs recovery from 50 mA → 350 mA step) - ideal for burst-mode wireless communication. |
| 6 MHz fixed-frequency PWM | Enables use of 0.5 µH shielded inductors and 0402 MLCCs, achieving total solution size <7 mm² - critical for slim smartphone and wearable form factors. |
| ±1.5% output voltage accuracy | Guaranteed over −30°C to +125°C junction temperature and full load range - ensures reliable operation of 2.8–3.0 V I/O and memory interfaces. |
| Internal soft-start | Gradually ramps output voltage during EN assertion to limit inrush current into downstream capacitance - prevents brownout in shared power rails. |
| Synchronous rectification | Eliminates external Schottky diode; achieves >90% efficiency at 3.6 VIN/2.9 VOUT/300 mA - reduces heat generation in thermally constrained modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62231DRYR | Fixed 2.9 V output, 600 mA, 3.6 MHz switching, 22 µA IQ in PFM - slightly lower frequency and marginally better light-load efficiency. | Same DSBGA-6 package (1.0 × 1.4 mm), but requires different layout due to pinout shift (EN/FB swapped); no MODE pin - lacks user-selectable forced PWM. | Select when prioritizing lowest possible IQ and simpler control logic, accepting loss of manual PWM override capability. |
| RT8059GJ6 | Fixed 2.9 V, 600 mA, 6 MHz, 25 µA IQ in PFM - comparable efficiency curve but higher RDS(ON) (280/240 mΩ) and no thermal shutdown. | TSOT-23-6 package (2.9 × 1.6 mm) - 3× larger footprint; lacks integrated soft-start and UVLO hysteresis - requires external circuitry for robust startup. | Select only for cost-sensitive, non-safety-critical applications where board space is not constrained and thermal monitoring is handled externally. |
Compared with TPS62231DRYR and RT8059GJ6, LM8801TME-2.9/NOPB uniquely combines 6 MHz operation, MODE-pin controllability, ±1.5% accuracy, and full protection suite in a 1.065 × 1.265 mm DSBGA - making it the preferred choice for next-generation mobile SoC power delivery where size, precision, and reliability are co-prioritized.

FAQ
What is the output voltage setting of the LM8801TME-2.9/NOPB?
The LM8801TME-2.9/NOPB is a fixed-output variant configured for 2.9 V with ±1.5% DC accuracy over temperature and load. Unlike adjustable versions (e.g., LM8801XUE-1.82/NOPB), it does not require external feedback resistors - the 2.9 V is internally trimmed and factory-set, simplifying design and reducing BOM count. This fixed value is confirmed in TI's ordering information table and electrical characteristics section.
Does the LM8801TME-2.9/NOPB support forced PWM mode?
Yes, the LM8801TME-2.9/NOPB supports forced PWM mode via the MODE pin: applying a logic HIGH (>1.2 V) to pin A1 disables automatic PFM/PWM transition and locks the device into continuous 6 MHz PWM operation across all load conditions. This is essential for noise-sensitive applications like RF sections where variable-frequency PFM could cause interference. The MODE pin function is explicitly defined in the Pin Descriptions section of the datasheet.
What package type and dimensions does the LM8801TME-2.9/NOPB use?
The LM8801TME-2.9/NOPB uses a 6-bump DSBGA package measuring 1.065 mm × 1.265 mm with 0.6 mm height (package codes YFQ0006LCA/YQA0006LCA). It features a non-solder-mask-defined (NSMD) pad layout and requires precision reflow per TI Application Note AN-1112. This ultra-compact footprint is validated for use with 0402 passives and enables total solution sizes under 7 mm².
What is the typical quiescent current of the LM8801TME-2.9/NOPB in PFM mode?
The LM8801TME-2.9/NOPB draws 27 µA (typical) quiescent current in PFM mode at no load, as specified in the Electrical Characteristics table under "IQ_PFM". This ultra-low IQ enables extended battery standby time in always-on mobile subsystems. Measured values remain within 27–35 µA across the full −30°C to +85°C ambient range, with no additional external components required to achieve this performance.
How does the LM8801TME-2.9/NOPB handle overcurrent and thermal faults?
The LM8801TME-2.9/NOPB integrates current limiting (1.1 A typical PFET peak limit) and thermal shutdown (engages at ~150°C junction, resumes at ~130°C). During overload, it enters timed current limit mode - extending NFET conduction to allow inductor current decay - preventing runaway. These protections are fully internal and require no external components. The shutdown behavior is verified in the Absolute Maximum Ratings and Operation Description sections of the datasheet.
