Product details
Overview
The MAXM15062AMB+T from Maxim Integrated is a fixed 3.3V, 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 for stable regulation in space-constrained industrial sensor and 4–20mA loop-powered applications.
For engineers reviewing the MAXM15062AMB+T datasheet, MAXM15062AMB+T pinout, MAXM15062AMB+T application, or MAXM15062AMB+T equivalent, key selection criteria include its 3.3V fixed output, 4.1ms soft-start, hiccup overcurrent protection, -40°C to +125°C ambient operation, and uSLIC™ package compatibility with high-density PCB layouts.
Technical Context
The MAXM15062AMB+T implements peak-current-mode control with internal compensation, enabling stable regulation without external loop components. Its fixed 3.3V output is set by internal feedback resistors-FB connects directly to OUT-eliminating external divider requirements.
It supports programmable enable/UVLO via EN/UVLO (1.215V typical rising threshold), offers selectable PWM/PFM operation via MODE pin, and integrates thermal shutdown (166°C) with 10°C hysteresis and hiccup-mode overcurrent protection for robust fault handling in unattended systems.
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 3.3V ±1.5% - eliminates external feedback resistor network; suitable for powering microcontrollers, sensors, and analog circuitry. |
| Max Output Current | 300mA - sufficient for point-of-load regulation in low-power IoT nodes and encoder interfaces. |
| Switching Frequency | 465kHz to 535kHz - enables compact external capacitor selection and predictable EMI filtering design. |
| Soft-Start Time | 4.1ms (typ) - limits inrush current during power-up, reducing stress on input capacitors and upstream supplies. |
| Operating Temperature | -40°C to +125°C ambient - qualified for harsh environments including HVAC control and industrial enclosures. |
| Shutdown Current | 2.2μA (typ) - enables ultra-low quiescent power in battery-backed or energy-harvesting systems. |
Pinout & Package
Package: 10-pin uSLIC™ (2.6mm × 3mm × 1.5mm, M102A3+2 outline), RoHS-compliant, surface-mount with exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 LX | Switching node | Internal connection to power inductor; no external component required; must be routed with minimal loop area for EMI control. |
| 2 GND | Power ground | Main return path for high-current switching; requires low-impedance connection to PCB ground plane. |
| 3 RESET | Open-drain power-good | Asserts low when FB falls below 92% of target; pulled high externally to monitor system readiness before processor boot. |
| 4 MODE | PFM/PWM mode select | GND = forced PWM; floating = automatic PFM at light load for higher efficiency in standby. |
| 5 OUT | Regulated output | 3.3V power rail; requires ≥10µF ceramic output capacitor placed adjacent to pin for stability and transient response. |
| 6 FB | Feedback input | Internally tied to 3.3V output; no external divider needed-simplifies layout and improves accuracy vs. discrete solutions. |
| 7 VCC | LDO output | 5V internal supply; bypassed with ≥1µF ceramic capacitor to support gate drive and internal logic. |
| 8 EN/UVLO | Enable/UVLO input | Active-high; 1.215V rising threshold enables programmable turn-on voltage using resistor divider from VIN. |
| 9–10 VIN | Input power | Dual pins for lower impedance; must be decoupled together with ≥1µF ceramic capacitor near GND pin. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated inductor & MOSFETs | Eliminates 4–6 external components and layout sensitivity; reduces bill-of-materials and validation effort. |
| All-ceramic capacitor support | Enables use of small, reliable MLCCs instead of electrolytics-improving lifetime and temperature stability. |
| Prebias startup capability | Allows safe startup into precharged output rails (e.g., hot-swap or backup power scenarios) without damaging downstream loads. |
| CISPR-22 Class B compliance | Meets conducted/radiated emissions limits without external filter redesign-accelerating EMC certification. |
| Hiccup overcurrent protection | Auto-retries after fault clears, preventing thermal runaway while maintaining system visibility via RESET assertion. |

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 |
|---|---|---|---|
| MAXM15063AMB+T | Fixed 5V output; identical package, pinout, and electrical specs except FB and output voltage. | Used where 5V logic or USB-peripheral interface is required instead of 3.3V. | Select MAXM15063AMB+T only when system-level 5V rail is needed; not interchangeable without schematic revision. |
| RECOM R-78E3.3-0.5 | 3.3V/500mA module; wider input (6–36V); no MODE or RESET pins; lower efficiency at light load due to fixed-frequency operation. | Suitable for simpler designs lacking PFM or power-good monitoring requirements. | Choose RECOM R-78E3.3-0.5 for cost-sensitive, non-critical applications where RESET signaling and ultra-low IQ are unnecessary. |
Compared with MAXM15063AMB+T, the MAXM15062AMB+T provides tighter 3.3V regulation for modern low-voltage MCUs, while versus RECOM R-78E3.3-0.5 it adds critical features like programmable UVLO, hiccup protection, and PFM mode-justifying its use in mission-critical industrial endpoints.

FAQ
What is the output voltage tolerance of the MAXM15062AMB+T over temperature and load?
The MAXM15062AMB+T maintains ±1.5% output voltage regulation over -40°C to +125°C ambient temperature and full 0–300mA load range. This specification includes initial accuracy, line regulation, load regulation, and thermal drift-all guaranteed by design and production-tested at +25°C with characterization across the full operating range.
Does the MAXM15062AMB+T require external compensation components?
No, the MAXM15062AMB+T is internally compensated. Its peak-current-mode architecture and integrated compensation network eliminate the need for external RC networks or type-II/type-III compensators-reducing design risk and PCB area while ensuring stability with standard ceramic output capacitors.
Can the MAXM15062AMB+T be used in prebiased startup conditions?
Yes, the MAXM15062AMB+T supports prebias startup. When the OUT pin is precharged, the device safely ramps the output without reverse current flow or output overshoot-verified in application waveforms (e.g., toc59, toc60) for both PWM and PFM modes with 2V prebias at 24V input.
What is the absolute maximum input voltage rating for the MAXM15062AMB+T?
The absolute maximum input voltage for the MAXM15062AMB+T is 70V applied to VIN or EN/UVLO pins. This rating allows safe operation during load-dump transients in industrial 48V systems, though continuous operation is specified up to 60V per the recommended operating conditions table.
How does the RESET pin function on the MAXM15062AMB+T?
The RESET pin on the MAXM15062AMB+T is an open-drain output that pulls low when FB falls below 92% of its nominal value (3.3V), indicating undervoltage. It transitions to high-impedance 2ms after FB rises above 95.5% of 3.3V, providing a clean power-good signal for microcontroller reset sequencing in the MAXM15062AMB+T.
