Analog Devices Inc./Maxim Integrated MAXM15467AMB+T

Overview

The MAXM15467AMB+T 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, features ±1.5% feedback accuracy, 550kHz switching frequency, and 3.75ms soft-start - enabling compact, low-noise point-of-load regulation for industrial sensors and battery-powered equipment.

For engineers reviewing the MAXM15467AMB+T datasheet, MAXM15467AMB+T pinout, MAXM15467AMB+T application, or MAXM15467AMB+T equivalent, key selection considerations include its 0.9V–6.3V adjustable output range, open-drain RESET output with 95.5% rising threshold, hiccup overcurrent protection, -40°C to +125°C ambient operation, and compliance with CISPR22 Class B emissions.

Technical Context

The MAXM15467AMB+T employs peak-current-mode control architecture with internal compensation, eliminating external loop components. Its programmable EN/UVLO threshold (1.19V–1.28V rising) and prebias startup capability support robust power sequencing in multi-rail systems.

It integrates a 5V LDO (VCC) with 4.75V–5.25V output and 30mA current limit, supplies internal circuitry, and enables self-biasing. The device supports selectable PWM or PFM mode via the MODE pin, optimizing efficiency across light-to-full load conditions while maintaining stable regulation under transient loads.

FAQ

What is the output voltage range supported by the MAXM15467AMB+T?

The MAXM15467AMB+T supports an adjustable output voltage range from 0.9V to 6.3V, set using an external resistor divider connected to the FB pin. This range covers common logic levels (1.8V, 2.5V, 3.3V), analog supply rails (5V), and low-voltage cores (0.9V), making the MAXM15467AMB+T adaptable across diverse subsystem requirements without redesign.

Does the MAXM15467AMB+T require external compensation components?

No, the MAXM15467AMB+T is internally compensated - all compensation components are integrated within the module. This eliminates the need for external Type-II or Type-III compensation networks, significantly simplifying design, reducing bill-of-materials count, and improving consistency across production units. The MAXM15467AMB+T achieves stable operation across its full input/output range with only input and output ceramic capacitors.

How does the RESET pin on the MAXM15467AMB+T function?

The RESET pin on the MAXM15467AMB+T is an open-drain power-good indicator that goes low when the FB voltage drops below 92% of its regulated value and transitions to high-impedance 1.9ms after FB rises above 95.5%. It requires an external pull-up resistor to a valid supply rail. This behavior enables reliable system-level power monitoring and reset assertion in the MAXM15467AMB+T's host application.

What thermal performance can be expected from the MAXM15467AMB+T in a standard four-layer PCB layout?

In a standard four-layer PCB layout with adequate copper pour, the MAXM15467AMB+T exhibits a junction-to-ambient thermal resistance (θJA) of 41.56°C/W. With its -40°C to +125°C ambient operating range and 150°C maximum junction temperature, this allows continuous 300mA output at up to +85°C ambient when properly heatsinked - verified in Maxim's evaluation kit layout referenced in the datasheet.

Can the MAXM15467AMB+T operate with a prebiased output voltage during startup?

Yes, the MAXM15467AMB+T supports prebias startup - it safely starts into an already charged output rail without causing reverse current or latch-up. This capability is critical in hot-swap, redundant power, and multi-rail sequencing applications. The MAXM15467AMB+T maintains controlled gate drive timing and internal state management to ensure clean, deterministic startup even when VOUT is initially non-zero.
