The MAX20412 is a dual-output, high-efficiency, synchronous step-down controller IC that operates with a 3.0V to 5.5V input voltage range and provides a 0.25V to 1.275V output voltage range. The controller architecture enables up to 30A of load current per phase. Channel 1 has an option to operate with two phases to deliver higher load current, making this device ideal for automotive point-of-load (PoL) and post-regulation applications. The IC achieves ±2% output error over load, line, and temperature ranges. The IC features a 2.2MHz/1.1MHz fixed-frequency PWM mode for better noise immunity and load-transient response, and a pulse-frequency modulation mode (skip) for increased efficiency during light-load operation. The 2.2MHz frequency operation allows the use of all-ceramic capacitors and minimizes external components. The programmable spread-spectrum frequency modulation minimizes radiated electromagnetic emissions. The MAX20412 is offered with factory-preset output voltages (see the Selector Guide for options). The I2C interface supports dynamic voltage adjustment with programmable slew rates for each channel. Other features include programmable soft-start, overcurrent, and overtemperature protections.Applications * Automotive * Core Processor System/GPU Power * 2-Channel, High-Efficiency DC-DC Controller in a Small Solution Size * 3.0V to 5.5V Operating Supply Voltage * OUT1 Supports 60A (with Two Phases) * OUT2 Supports 30A * High-Precision Regulator for Applications Processors * ±2% Output-Voltage Accuracy * Differential Remote-Voltage Sensing * I2C-Controlled Output Voltage: 0.25V to 1.275V in 6.25mV Steps * Excellent Load-Transient Performance * Programmable Compensation * Low-Noise Features Reduce EMI * 2.2MHz or 1.1MHz Operation * Spread-Spectrum Option * Frequency-Synchronization Input/Output * Current-Mode, Forced-PWM, and Skip Operation * Robust for the Automotive Environment * Individual Enable Inputs and PGOOD Outputs * Low RDS(ON) External MOSFETs * Overtemperature and Short-Circuit Protection * 32-Pin (5mm x 5mm) TQFN with Exposed Pad * -40°C to +125°C Operating Temperature Range * AEC-Q100 Qualified https://elecena.pl/product/22320729/automotive-low-voltage-2-channel-step-down-controller 2022-12-27 https://elecena.pl/product/22320729/automotive-low-voltage-2-channel-step-down-controller 2024-02-08 https://elecena.pl/product/22320729/automotive-low-voltage-2-channel-step-down-controller 2024-08-09 https://elecena.pl/product/22320729/automotive-low-voltage-2-channel-step-down-controller 2025-01-17
