Analog Devices / Maxim Integrated MAX20499 Automotive Step-Down Converters

Analog Devices MAX20499 Automotive Step-Down Converters operate with a 3.0V to 5.5V input voltage range and supply a 0.5V to 1.275V output voltage range. The wide input/output voltage range and the ability to provide up to 12A peak output current make this device family ideal for on-board point-of-load and post-regulation applications. The MAX20499 achieves ±1.5% output error over load, line, and temperature ranges. The MAX20499 features a 2.2MHz fixed-frequency PWM mode for better noise immunity and load-transient response.
