MAX20430 Overview
Description
The MAX20430 is a high-efficiency, four-output DC-DC converter and windowed watchdog. OUT1 is a synchronous step-down converter that converts vehicle battery voltage to 3.3V at up to 2.5A.
Key Features
- 2.1MHz fixed-frequency PWM mode for all DC-DC outputs for better noise immunity and loadtransient response
- The 2.1MHz frequency operation allows for the use of all ceramic capacitors and minimizes external components
- The programmable spread-spectrum frequency modulation minimizes radiated electromagnetic emissions
- Integrated low RDSON switches improve efficiency at heavy loads and make the layout much simpler with respect to discrete solutions
- The device is offered with factory-preset output voltages
- Other features include soft-start, overcurrent, and overtemperature protections
