Key Features
- 4.5 V to 40 V wide input range covers automotive 12 V and 24 V battery rails plus full cold-crank and load-dump transient conditions
- Current-mode PWM control with cycle-by-cycle overcurrent limiting enables fast transient response and inherent short-circuit protection in flyback/boost/SEPIC topologies
- AEC-Q100 automotive qualification ensures reliable operation across -40°C to +125°C junction temperature for in-vehicle power supply designs
- Adjustable switching frequency and programmable soft-start minimize EMI and inrush current in under-hood automotive and industrial converter designs
Applications
The MAX15005BAUE/V+ is used in automotive DC/DC power converters supplying infotainment systems, ADAS sensor modules, and LED lighting drivers where the input rail ranges from 4.5 V to 40 V and isolated or non-isolated flyback, boost, or SEPIC topologies are required. It suits industrial 12 V and 24 V battery-powered equipment such as handheld barcode scanners and battery management units where adjustable switching frequency from tens of kHz to hundreds of kHz reduces filter component size. Its current-mode architecture and wide input range also make it a practical choice for battery charger and UPS front-end designs targeting 14 V nominal automotive bus voltage with tolerance for transients up to 40 V.

Frequently Asked Questions
What input voltage range does MAX15005BAUE/V+ support, and which automotive battery conditions does this cover?
The MAX15005BAUE/V+ operates across a 4.5 V to 40 V input range, which covers the full automotive 12 V battery envelope including cold-crank lows near 6 V, normal operation at 14 V charging voltage, and load-dump transients reaching 36 V to 40 V per ISO 7637-2 specifications. The 14 V nominal input rating is optimized for 12 V automotive systems, but the range also covers 24 V truck battery buses up to 30 V continuous.
How does current-mode PWM control in MAX15005BAUE/V+ benefit flyback converter designs compared to voltage-mode control?
Current-mode PWM control in the MAX15005BAUE/V+ provides cycle-by-cycle current limiting without external sense amplifiers, automatically balancing transformer flux and preventing core saturation in flyback converters running at switching frequencies from 50 kHz to 500 kHz. Compared to voltage-mode control, the inner current loop improves line transient rejection by approximately 20 dB and reduces the compensation network complexity from a type-3 to a type-2 error amplifier design, simplifying loop stabilization for input voltages varying from 4.5 V to 40 V.
For a 12 V automotive system, what power conversion topologies can the MAX15005BAUE/V+ controller directly support?
The MAX15005BAUE/V+ directly supports three non-inverting or isolated DC/DC topologies from a 12 V automotive rail: flyback (for isolated outputs with a single switch), boost (for stepping up from 12 V to 24 V or higher), and SEPIC (for output voltages above or below the 12 V input with continuous input current). This multi-topology flexibility means one controller IC family handles diverse power needs across infotainment, sensor, and lighting subsystems in a vehicle platform, reducing the number of unique controller SKUs in the bill of materials.
What package does MAX15005BAUE/V+ use and how does it fit into a compact automotive power module layout?
The MAX15005BAUE/V+ is housed in a 16-pin TSSOP (4.4 mm × 4.4 mm body) package with 0.65 mm pin pitch, occupying approximately 19 mm² of PCB footprint including pad land. This is significantly smaller than a comparable 16-pin SOIC package (approximately 60 mm²), making the TSSOP format advantageous for automotive power modules constrained to board areas under 40 mm × 40 mm, such as ADAS camera power supplies or compact ECU DC/DC converter sub-circuits.
