Automotive Single 8A/12A Step-Down

Converter Family

MAX20499

General Description

Benefits and Features

The MAX20499 is a family of high-efficiency, synchronous

step-down converters that operate with a 3.0V to 5.5V in-

put voltage range and supply a 0.5V to 1.275V output volt-

age 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.

● High-Efficiency DC-DC Converter

● Up to 12A Peak Output Current

• MAX20499A: 8A

• MAX20499B: 12A

● Differential Remote Voltage Sensing

● 3.0V to 5.5V Operating Supply Voltage

● I C-Controlled Output Voltage: 0.5V to 1.275V in

6.25mV Steps

The MAX20499 features a 2.2MHz fixed-frequency PWM

mode for better noise immunity and load-transient re-

sponse. The 2.2MHz frequency operation allows for the

use of all ceramic capacitors and minimizes external com-

ponents. The spread-spectrum frequency modulation op-

tion minimizes radiated electromagnetic emissions. Inte-
