Product details
Overview
MAXM15467AMB+ from Maxim Integrated is an adjustable-output, synchronous step-down DC-DC power module integrating controller, MOSFETs, compensation, and inductor in a single uSLIC™ package. It operates from 4.5V to 42V input, delivers up to 300mA output current, supports 0.9V–6.3V adjustable output voltage with ±1.5% feedback accuracy, and features peak-current-mode control with 3.75ms soft-start - enabling compact, low-noise point-of-load regulation for industrial sensors and battery-powered equipment.
For engineers reviewing the MAXM15467AMB+ datasheet, MAXM15467AMB+ pinout, MAXM15467AMB+ application, or MAXM15467AMB+ equivalent, this page provides verified technical context, validated pin functions, real-world application mappings, and confirmed alternative options for design-in and supply chain continuity.
Technical Context
The MAXM15467AMB+ employs peak-current-mode control architecture with internal compensation, eliminating external loop components. Its fixed 550kHz nominal switching frequency (515–585kHz) enables predictable EMI filtering and stable operation across input voltages from 4.5V to 42V and load currents up to 300mA.
It integrates programmable EN/UVLO threshold (1.19–1.28V rising), open-drain RESET output with 95.5% rising/92% falling FB thresholds, and hiccup-mode overcurrent protection. Thermal shutdown activates at +166°C with 10°C hysteresis, supporting operation from –40°C to +125°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5V to 42V - supports wide industrial and automotive input rails without pre-regulation. |
| Output Voltage Range | Adjustable 0.9V to 6.3V - set via external resistor divider on FB pin; enables flexible SoC core or peripheral rail generation. |
| Max Output Current | 300mA - sufficient for microcontrollers, sensors, and low-power FPGAs in space-constrained designs. |
| Feedback Accuracy | ±1.5% - ensures tight output regulation under line/load/temperature variation for precision analog or digital loads. |
| Switching Frequency | 515kHz to 585kHz - fixed-frequency PWM mode enables deterministic EMI filter design and avoids audible noise. |
| Soft-Start Time | 3.75ms (typ) - prevents inrush current during power-up, protecting upstream sources and downstream capacitors. |
| Shutdown Current | 2.2μA (typ) - ultra-low quiescent draw extends battery life in always-on sensor nodes. |
Pinout & Package
MAXM15467AMB+ uses a 10-pin, 2.6mm × 3mm × 1.5mm uSLIC™ package (package code M102A3+2), optimized for high-density PCB layouts and thermal performance on four-layer boards (θJA = 41.56°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - LX | Switching node | Internal connection to integrated inductor and high-side MOSFET drain; no external connection required. |
| 2 - GND | Power ground | Main return path for input/output currents; must be connected to low-impedance ground plane per layout guidelines. |
| 3 - RESET | Open-drain power-good | Asserts low when FB falls below 92% of regulation; pulled high externally to indicate valid output voltage after 1.9ms delay. |
| 4 - MODE | PFM/PWM selection | Connect to GND for forced PWM; leave unconnected for automatic PFM/PWM transition to optimize light-load efficiency. |
| 5 - OUT | Regulated output | Delivers final regulated voltage; connects directly to load and output capacitor (10µF ceramic typical). |
| 6 - FB | Feedback input | Senses output voltage via external resistor divider; sets output voltage as VOUT = VFB-REG × (1 + R1/R2), where VFB-REG = 0.90V (typ). |
| 7 - VIN | Main input supply | Accepts 4.5V–42V input; requires 1µF ceramic input capacitor placed close to pin for stability and ripple suppression. |
| 8 - EN/UVLO | Enable/undervoltage lockout | Active-high enable with 1.19–1.28V rising threshold; disables regulator if input drops below UVLO falling threshold (1.06–1.16V). |
| 9 - VCC | Internal LDO output | Provides 5.0V ±2.5% at up to 30mA for internal circuitry; bypassed with 1µF ceramic capacitor. |
| 10 - NC | No connect | Internally unused; must remain unconnected per datasheet. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated inductor + controller + MOSFETs | Eliminates 12+ external components and reduces solution footprint by >50% vs discrete buck designs. |
| All-ceramic capacitor support | Enables compact, low-profile designs without electrolytic or tantalum capacitors - improving reliability and lifetime. |
| Selectible PFM/PWM operation | Extends battery runtime in IoT sensors by reducing light-load quiescent current to 95μA (typ) in PFM mode. |
| CISPR-22 Class B compliance | Meets conducted/radiated EMI limits without external filters in typical layouts - accelerates EMC certification. |
| Hiccup overcurrent + thermal protection | Prevents damage during sustained overload or poor heatsinking; auto-recovery avoids system latch-up. |
| Prebias startup capability | Allows safe start-up into precharged output rails - critical for hot-swap and redundant power systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar adjustable-output buck module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAXM15462AMB+ | Same Himalaya uSLIC™ family; 600mA output current, identical 4.5–42V input, but larger 3mm × 4mm package. | Higher current demand (e.g., FPGA I/O banks or dual-core MCUs); requires PCB layout revision for larger footprint. | Select MAXM15462AMB+ only when >300mA continuous load is required; otherwise MAXM15467AMB+ offers better size/cost trade-off. |
| TSM10831DQNR | TI's 300mA adjustable buck module; 4.5–60V input, 0.8–15V output, but uses different 3mm × 3.5mm QFN package and lacks integrated inductor shielding. | Higher input voltage tolerance needed (e.g., 48V telecom); less EMI robustness in dense layouts due to exposed inductor. | Choose TSM10831DQNR only for >42V input requirements; MAXM15467AMB+ provides superior EMI performance and smaller height (1.5mm vs 2.0mm). |
Compared with MAXM15462AMB+, MAXM15467AMB+ saves board area and cost for ≤300mA loads; compared with TSM10831DQNR, it delivers lower radiated emissions and tighter thermal profile in constrained spaces.

FAQ
What is the minimum output voltage supported by the MAXM15467AMB+?
The MAXM15467AMB+ supports an adjustable output voltage range from 0.9V to 6.3V. This minimum 0.9V output is enabled by its precise 0.90V (typ) internal feedback reference voltage and ±1.5% accuracy, making it suitable for powering modern low-voltage microcontrollers and ASIC cores that require sub-1V rails.
Does the MAXM15467AMB+ require external compensation components?
No, the MAXM15467AMB+ is internally compensated. Its peak-current-mode control architecture and integrated compensation network eliminate the need for external Type-II or Type-III compensation networks, simplifying design and reducing bill-of-materials count while maintaining stability across all operating conditions.
How does the RESET pin on the MAXM15467AMB+ behave during startup and fault conditions?
The RESET pin on the MAXM15467AMB+ is an open-drain output that goes high-impedance 1.9ms after the FB voltage rises above 95.5% of its regulation target. It pulls low if FB falls below 92% of target - indicating undervoltage or overload. An external pull-up resistor is required to generate a logic-high signal for system monitoring.
Can the MAXM15467AMB+ operate with a prebiased output voltage?
Yes, the MAXM15467AMB+ supports prebias startup. When enabled via the EN/UVLO pin, it safely ramps the output from an existing voltage (e.g., 2V) to the target level without injecting reverse current into the output capacitor - essential for hot-swap and redundant power architectures.
What is the thermal performance of the MAXM15467AMB+ on a standard PCB?
On a four-layer evaluation board with natural convection, the MAXM15467AMB+ exhibits a junction-to-ambient thermal resistance (θJA) of 41.56°C/W. At full 300mA load and 24V input, typical junction temperature rise is ~35°C above ambient - well within its –40°C to +150°C junction limit and enabling reliable operation without forced airflow.
