• More About Maxim IC

The MAX15041 Step-Down DC/DC Regulator from Maxim IC is a low-cost, synchronous DC-DC converter with an internal switch that delivers an output current up to 3A. Maxim's MAX 15041 Series Step-Down DC/DC Regulator operates from an input voltage range of 4.5V to 28V and features a peak-current-mode PWM controller with an internally fixed 350kHz switching frequency and a 90% maximum duty cycle. This synchronous buck regulator also features internal MOSFETs that provide better efficiency than asynchronous solutions, thermal shutdown, overcurrent protection (high-side sourcing and low-side sinking), an internal 5V LDO with undervoltage lockout, and more. In addition, Maxim's MAX 15041 regulator ensures safe startup when powering into a prebiased output.
