Inquire About This Product
basic information
This product is a step-down DC/DC converter with a built-in driving transistor that operates at 30V. The output voltage can be set from 1.2V to 12V due to internal resistance. The switching frequency can be selected between 300kHz and 500kHz. The soft start time can be set to any value by adding internal capacitance. With the built-in UVLO function, the driving transistor is forcibly turned off when the input voltage drops below 4.5V. It also includes internal protection circuits for overcurrent protection, short circuit protection, and overheat protection, ensuring safe use.
