The MAX20431B/MAX20432B are high-efficiency, four-/ three-output DC-DC converters with a windowed watchdog. The OUT1 is a synchronous step-down converter that converts vehicle battery voltage to 3.3V at up to 2.5A. The OUT3 boosts the OUT1 to 5V at up to 500mA, while the OUT2/OUT4 (MAX20431B) or OUT2 (MAX20432B) low-voltage synchronous step-down converters operate from OUT1 and provide a 0.5V to 3.6875V output voltage range at up to 3A. All outputs achieve ±1.5% output error over load, line, and temperature range.The devices feature a 2.1MHz fixed-frequency PWM mode for all DC-DC outputs for better noise immunity and load-transient response. The 2.1MHz frequency operation allows for the use of all ceramic capacitors and minimizes the external components. The programmable spread-spectrum frequency modulation minimizes the radiated electromagnetic emissions. Integrated low RDSONswitches improve efficiency at heavy loads and make the layout much simpler with respect to discrete solutions.The devices features the MAXQ®power architecture, which provides precision transient performance and phase margin. This allows to obtain the maximum power, performance, and precision while minimizing system cost for any specific application.The devices are offered with factory-preset output voltages. Other features include soft-start, overcurrent, and overtemperature protection.
YG GROUP supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
MAX20431B is an authentic electronic component manufactured by Analog Devices, categorized under Power Management ICs. It is supplied in the standard manufacturer-specified package footprint, providing industry-standard mechanical dimensions and terminal configurations for board-level assembly. Full pinout configurations, physical footprint drawings, and rated operating tolerances are documented in the official MAX20431B datasheet above.
Electronic component spot-market pricing for MAX20431B fluctuates based on real-time global availability, production date codes, minimum order quantities (MOQ), and packaging formats (e.g., Reel, Tube, Tray). Using an RFQ ensures you receive accurate, real-time volume pricing tied to verified, traceable inventory rather than stale catalog estimates.
Lead times for MAX20431B depend on whether stock is dispatched from our central hub or regional franchise partners. Ready-to-ship inventory typically leaves the warehouse within 1–3 business days following quality inspection, while factory-direct or back-ordered allocations are confirmed with an estimated ship date upon RFQ reply.
