Key Features
- Wide 4.5V to 42V input range with 300mA output current, supporting 24V industrial bus and automotive battery rail step-down conversion
- Fully integrated inductor in a 3x2.6x1.5mm 10-pin BGA module eliminates external magnetics, reducing total solution size by up to 60%
- Current-mode PWM control architecture provides fast transient response and cycle-by-cycle current limiting for robust short-circuit protection
Applications
The MAXM15462AMB+T is designed for point-of-load regulation on industrial sensor nodes, field instruments, and 24V PLC I/O modules where board space is tightly constrained. Its 4.5V to 42V input range accommodates 12V, 24V, and 36V power rails common in factory automation, enabling a single BOM item across multiple voltage domains. The integrated inductor module simplifies PCB layout and passes EMI compliance more easily than discrete buck converters in space-limited enclosures.

Frequently Asked Questions
What input voltage range and output current does the MAXM15462AMB+T support in industrial 24V systems?
The MAXM15462AMB+T accepts input voltages from 4.5V to 42V and delivers up to 300mA of output current. This covers the full range of 24V nominal industrial rails that may swing from 18V to 36V under load and transient conditions. The device can also step down from 12V automotive or telecom rails, making it versatile for multi-rail industrial system designs with a single power module.
How does the integrated inductor in the MAXM15462AMB+T simplify PCB layout compared to a discrete buck regulator?
The MAXM15462AMB+T integrates the switching inductor directly into its 3x2.6x1.5mm BGA package, eliminating the need for an external inductor footprint that typically requires 2mm to 5mm of additional PCB area. This reduces the total power supply solution area by up to 60% and removes the inductor placement and orientation considerations that affect radiated EMI. Engineers avoid the need to select and source a separate inductor, which also simplifies the BOM and procurement process.
How does the MAXM15462AMB+T's current-mode PWM control protect circuits from short-circuit faults at 42V input?
The current-mode PWM architecture of the MAXM15462AMB+T monitors inductor current on a cycle-by-cycle basis and clamps peak current to a preset limit, typically around 600mA, before damage can occur. At the maximum 42V input, a short-circuit at the output would otherwise dissipate significant power, but the cycle-by-cycle limiting reduces switch-on time within each PWM cycle to keep power dissipation within the thermal limits of the 10-pin BGA package. The device also enters hiccup mode during sustained short-circuit conditions, further limiting average power dissipation to safe levels.
