Description
General part information
MAX20438 Series
The MAX20438 is an ultra-high-efficiency switching regulator that delivers up to 12A load current from 0.5V to 1.2V. The IC operates from 2.5V to 5.5V, making it ideal for on-board, point-of-load (PoL) and post regulation applications. The total output error is less than ±1.0% over load, line, and temperature.The MAX20438 features adaptive on-time with a switching frequency of 2.1MHz or 4.2MHz. High-frequency operation allows for small-size, all-ceramic capacitor design.The low-resistance, on-chip switches ensure high efficiency at heavy loads while minimizing critical inductances, making the layout a much simpler task with respect to discrete solutions.The device features the MAXQ™power architecture which provides precision transient performance and phase margin. This allows obtaining the maximum power, performance, and precision from the converter over a very wide range of configurations.The output voltage is preset at the factory to allow customers to achieve ±1% output-voltage accuracy without using expensive 0.1% resistors. The device offers factory-programmable soft-start andRESETtimes.The device includes overtemperature shutdown and overcurrent limiting. The MAX20438 is designed to operate in the -40°C to +125°C ambient temperature range.APPLICATIONSSecondary Regulator for SoC/MCU SupplyPoL and Post-Regulation Applications
