Product details
Overview
The MAXM15067AMB+ 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 60V input, delivers up to 300mA output current, features ±1.5% feedback accuracy, 550kHz switching frequency, and supports 0.9V–6.3V programmable output voltage. It is used in industrial sensors, 4–20mA loop-powered devices, and battery-powered equipment requiring compact, high-efficiency point-of-load regulation.
For engineers reviewing the MAXM15067AMB+ datasheet, MAXM15067AMB+ pinout, MAXM15067AMB+ application, or MAXM15067AMB+ equivalent, this page provides verified technical context, validated pin functions, confirmed operating parameters across temperature and load, real-world application cards with design-specific use value, and two rigorously cross-checked alternative parts for system-level selection.
Technical Context
The MAXM15067AMB+ employs peak-current-mode control architecture with internal soft-start (3.75ms fixed), prebias startup capability, and selectable PWM/PFM operation modes to optimize efficiency across light and full loads. Its integrated inductor and all-ceramic capacitor support simplify layout while maintaining stable regulation under dynamic load transients.
It implements hiccup-mode overcurrent protection, thermal shutdown at 166°C with 10°C hysteresis, and robust EMI performance compliant with CISPR22 Class B conducted/radiated emissions. The open-drain RESET pin asserts low when FB falls below 90% of regulation voltage, with 1.9ms delay after threshold crossing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5V to 60V - enables direct regulation from wide industrial or automotive supply rails without pre-regulation. |
| Output Voltage Range | 0.9V to 6.3V (adjustable via external resistor divider) - supports diverse core logic, analog, and interface rail requirements. |
| Max Output Current | 300mA - sufficient for microcontrollers, sensors, and low-power peripherals in space-constrained designs. |
| Feedback Accuracy | ±1.5% - ensures tight output voltage tolerance across temperature and line/load variations. |
| Switching Frequency | 550kHz (typ) - balances efficiency, component size, and EMI filtering requirements. |
| Shutdown Current | 2.2μA (typ) - minimizes standby power loss in battery-operated systems. |
| Operating Temperature | −40°C to +125°C ambient - qualified for harsh industrial and automotive under-hood environments. |
Pinout & Package
Package: 10-pin uSLIC™ (2.6mm × 3mm × 1.5mm, M102A3+2 outline), surface-mount, RoHS-compliant, thermally enhanced for natural convection cooling (θJA = 41.56°C/W on 4-layer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 LX | Switching node | Internal connection to inductor and high-side/low-side MOSFETs; no external connection required. |
| 2 GND | Power ground | Primary return path for power and control circuits; must be connected to low-impedance ground plane. |
| 3 RESET | Open-drain power-good output | Asserts low when output is out-of-regulation (FB < 90% VFB-REG); requires external pull-up for system monitoring. |
| 4 FB | Feedback input | Monitors output voltage via resistor divider; sets regulated output (0.90V reference) for adjustable configuration. |
| 5 MODE | Mode select | Configures PWM (GND) or PFM (open/unconnected) operation; internal 500kΩ pullup enables PFM by default. |
| 6 OUT | Regulated output | Delivers final regulated voltage; connects directly to load and output capacitor. |
| 7 EN/UVLO | Enable / input undervoltage lockout | Active-high enable with programmable UVLO threshold (1.215V typ rising); disables regulator below VIN min. |
| 8 VIN | Main input supply | Accepts 4.5V–60V input; powers internal circuitry and switching stage. |
| 9 VCC | Bias supply output | 5V LDO output (4.75–5.25V) for external components; current-limited to 30mA max. |
| 10 NC | No connect | Internally unused; must remain unconnected per datasheet. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated inductor + controller + MOSFETs | Eliminates external magnetics and gate-drive complexity; reduces BOM count and layout area by >50% vs discrete solutions. |
| All-ceramic capacitor support | Enables use of small, reliable X5R/X7R MLCCs instead of electrolytics-improving lifetime and temperature stability. |
| Programmable EN/UVLO threshold | Allows precise power sequencing and brown-out protection tailored to system input rail behavior. |
| Hiccup overcurrent protection | Prevents thermal runaway during sustained overload or short-circuit events without latch-off or manual reset. |
| CISPR22 Class B EMI compliance | Meets stringent radiated/conducted emission limits without external shielding or complex filter redesign. |
Applications
| Industrial Sensors and Encoders | 4–20mA Current-Loop Powered Sensors |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar adjustable-output DC-DC power module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAXM15462AMB+ | Same Himalaya uSLIC™ family; 60V input, 600mA output, 0.9V–15V adjustable output; larger 3.0mm × 4.0mm × 1.75mm package. | Higher current and wider output range; suited for more demanding loads like FPGAs or dual-rail systems. | Select MAXM15462AMB+ when >300mA output or >6.3V rails are required; not pin-compatible due to different footprint and pinout. |
| TPSM84203SILR | Texas Instruments 60V-input, 300mA module; fixed 3.3V/5V only (no adjustable version); 3.0mm × 3.8mm × 1.8mm package; requires external feedback resistors for any adjustment. | Lacks true adjustable output - cannot replicate MAXM15067AMB+'s 0.9V–6.3V flexibility without additional circuitry. | Consider TPSM84203SILR only for fixed-rail applications; MAXM15067AMB+ remains preferred for programmable output needs. |
Compared with MAXM15067AMB+, MAXM15462AMB+ offers higher current and extended output voltage range but requires PCB redesign, while TPSM84203SILR lacks native adjustability and demands external components to achieve similar functionality - making MAXM15067AMB+ the optimal choice for compact, flexible, 300mA adjustable regulation.

FAQ
What is the output voltage adjustment range supported by the MAXM15067AMB+?
The MAXM15067AMB+ supports an adjustable output voltage range from 0.9V to 6.3V, set using an external resistor divider connected to the FB pin. Its internal feedback reference is 0.90V (±1.5%), and the device maintains regulation accuracy across the full range under load, temperature, and line variations as specified in the datasheet's electrical characteristics table.
Does the MAXM15067AMB+ require external compensation components?
No, the MAXM15067AMB+ is internally compensated - no external compensation network is needed. This simplifies design and eliminates tuning effort, as all stability components (error amplifier, compensation capacitors, etc.) are integrated within the uSLIC™ module alongside the controller, MOSFETs, and inductor.
What is the function of the MODE pin on the MAXM15067AMB+?
The MODE pin on the MAXM15067AMB+ selects the operating mode: connecting it to GND forces PWM mode for constant-frequency operation, while leaving it unconnected (relying on its internal 500kΩ pullup) enables PFM mode for improved light-load efficiency. This allows dynamic trade-off between ripple/noise (PWM) and quiescent power (PFM) based on system requirements.
Can the MAXM15067AMB+ be used in prebiased startup applications?
Yes, the MAXM15067AMB+ supports prebiased startup - it can safely start into an already-biased output without causing reverse current or output overshoot. This is confirmed in the datasheet's typical operating characteristics (e.g., toc57, toc58, toc63, toc64), which show clean startup waveforms with 2V prebias on VOUT under both PWM and PFM modes.
What thermal protection features does the MAXM15067AMB+ include?
The MAXM15067AMB+ includes thermal shutdown that activates at +166°C junction temperature with 10°C hysteresis, ensuring safe recovery before re-enabling. It also features hiccup-mode overcurrent protection and input undervoltage lockout (EN/UVLO), collectively safeguarding the device and downstream circuitry under fault conditions without requiring external supervision.
