MAX20430
Overview
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.
- 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.
