Product details
Overview
The MAXM15063AMB+ from Maxim Integrated is a fixed 5V, 300mA synchronous step-down DC-DC power module with integrated controller, MOSFETs, compensation, and inductor. It operates from 4.5V to 60V input, delivers ±1.5% feedback accuracy, features an open-drain RESET output, and employs peak-current-mode control in a compact 10-pin uSLIC™ package. It serves as a plug-and-play replacement for LDOs in industrial sensors and 4–20mA loop-powered systems.
For engineers reviewing the MAXM15063AMB+ datasheet, MAXM15063AMB+ pinout, MAXM15063AMB+ application, or MAXM15063AMB+ equivalent, key selection criteria include its 5V fixed output, 4.1ms soft-start, hiccup overcurrent protection, -40°C to +125°C ambient operation, and compliance with CISPR22 Class B emissions-critical for space-constrained, high-reliability industrial power rails.
Technical Context
The MAXM15063AMB+ implements peak-current-mode control with internal compensation, enabling stable regulation without external loop components. Its fixed 5V output is set by internal feedback resistors (VFB-REG = 4.93–5.07V), eliminating external divider requirements for this variant.
It supports dual operating modes via the MODE pin: PWM for consistent frequency (465–535kHz) and low-noise performance under full load, or PFM for ultra-low quiescent current (95μA typ) during light-load conditions-enabling high efficiency across 5mA–300mA output range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5V to 60V - supports wide industrial input rails including 12V, 24V, 36V, and 48V systems without pre-regulation. |
| Output Voltage | Fixed 5.00V ±1.5% - eliminates need for external feedback resistors; enables direct replacement of 5V LDOs. |
| Max Output Current | 300mA - sufficient for microcontrollers, sensors, and USB Type-C powered loads in compact designs. |
| Switching Frequency | 465–535kHz - allows use of small external capacitors and avoids AM radio band interference. |
| Soft-Start Time | 4.1ms (typ) - prevents inrush current during power-up, protecting upstream supplies and downstream circuitry. |
| Shutdown Current | 2.2μA (typ) - enables ultra-low-power standby in battery-backed or energy-harvesting applications. |
| Operating Temp | -40°C to +125°C ambient - qualified for harsh environments in HVAC, building control, and industrial encoders. |
Pinout & Package
Package: 10-pin uSLIC™ (2.6mm × 3mm × 1.5mm, M102A3+2 outline), surface-mount, RoHS-compliant, with integrated inductor and thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 LX | Switching node | Internal connection to power inductor; no external component required-reduces layout complexity and EMI risk. |
| 2 GND | Power ground | Primary return path for high-current switching; must be connected to low-impedance ground plane per PCB layout guidelines. |
| 3 RESET | Open-drain power-good | Signals valid output voltage (95.5% rising / 92% falling threshold); requires external pull-up for system monitoring or sequencing. |
| 4 MODE | PFM/PWM mode select | Ground for forced PWM (low noise); floating for automatic PFM at light load (high efficiency). |
| 5 OUT | Regulated output | 5V output node; requires ceramic capacitor (≥10μF) to GND for stability and transient response. |
| 6 FB | Feedback input | Internally tied to 5V output-no external resistor divider needed; simplifies design vs. adjustable variants. |
| 7 VCC | LDO output | 5V internal bias rail; bypassed with ≥1μF ceramic cap to GND for gate drive and control circuit stability. |
| 8 EN/UVLO | Enable/UVLO input | Active-high enable; resistor divider from VIN sets precise turn-on threshold (1.19–1.28V rising edge). |
| 9–10 VIN | Input power | Dual pins for low-inductance, high-current input path; must be shorted and decoupled with ≥1μF ceramic cap near pins. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated power stage | Combines controller, high-/low-side MOSFETs, compensation, and shielded inductor-eliminates 12+ external components. |
| All-ceramic capacitor support | Enables compact, reliable designs without electrolytic or tantalum capacitors-improves lifetime and temperature stability. |
| Hiccup overcurrent protection | Auto-recovering fault response prevents thermal runaway during sustained overload or short-circuit events. |
| CISPR22 Class B compliance | Meets conducted/radiated emission limits without external filtering-reduces EMC debug time and board area. |
| Prebias startup capability | Starts safely into precharged output (e.g., hot-swap or backup supply scenarios) without reverse current or latch-up. |
Applications
| Industrial Sensors and Encoders | 4–20mA Current-Loop Powered Sensors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down power module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAXM15062AMB+ | Fixed 3.3V output; identical package, pinout, and feature set except FB internally tied to 3.3V node. | Suitable where 3.3V logic rails dominate (e.g., ARM Cortex-M MCUs, SPI peripherals). | Select MAXM15062AMB+ only when 3.3V-not 5V-is required; not a drop-in replacement for MAXM15063AMB+. |
| LMZ31503RKGR | 3A output, 2.95–6V input, 3mm × 4.5mm QFN; higher current but narrower input range and different pinout. | Better suited for high-current 5V rails (e.g., FPGA I/O banks), but requires redesign due to non-compatible footprint and control interface. | Choose LMZ31503RKGR only when >300mA is needed; MAXM15063AMB+ remains optimal for space-constrained 300mA 5V applications. |
Compared with MAXM15062AMB+, the MAXM15063AMB+ provides higher output voltage for legacy 5V peripherals, while compared with LMZ31503RKGR, it offers superior input voltage range and smaller footprint at lower current-making it ideal for industrial IoT endpoints where size, input flexibility, and reliability outweigh raw current capacity.

FAQ
What is the output voltage tolerance of the MAXM15063AMB+?
The MAXM15063AMB+ provides a fixed 5.00V output with ±1.5% regulation accuracy over line, load, and temperature. This is achieved via internal feedback resistors calibrated to deliver 4.93V to 5.07V at 25°C, and 4.93V to 5.18V across the full -40°C to +125°C ambient range-ensuring compatibility with standard 5V logic interfaces without external trimming.
Does the MAXM15063AMB+ require external compensation components?
No, the MAXM15063AMB+ does not require external compensation components. It uses an internally compensated peak-current-mode control architecture optimized for its integrated power stage. All stability components-including error amplifier compensation-are embedded within the module, allowing direct use with only input and output ceramic capacitors per the recommended layout.
Can the MAXM15063AMB+ operate with a prebiased output?
Yes, the MAXM15063AMB+ supports prebias startup. When enabled via the EN/UVLO pin, it safely starts into an already charged output (e.g., 2–4V) without forcing reverse current or causing output overshoot. This capability is verified in typical operating characteristics (toc53, toc54, toc59, toc60) and makes it suitable for hot-swap and redundant power applications.
What is the purpose of the MODE pin on the MAXM15063AMB+?
The MODE pin on the MAXM15063AMB+ selects between PWM and PFM operating modes. When grounded, it forces fixed-frequency PWM operation (465–535kHz) for consistent EMI profile and low-noise performance. When left unconnected, it enables automatic PFM mode at light loads (<10% of full scale), reducing quiescent current to 95μA typical and improving light-load efficiency-ideal for battery-backed sensor nodes.
How does the RESET pin function on the MAXM15063AMB+?
The RESET pin on the MAXM15063AMB+ is an open-drain power-good indicator. It pulls low when the FB voltage falls below 92% of its nominal value (e.g., <4.60V for 5V output) and transitions to high-impedance 2ms after FB rises above 95.5% (e.g., >4.78V). An external pull-up resistor is required to interface with microcontroller reset inputs or system supervisors.
