Product Description

36V 600mA PWM/PFM Synchronous Step-Down Micro DC/DC Converter

The XCL231 is a synchronous step-down Micro DC/DC converter with integrated coil in an ultra-small 3.0 x 3.0 x 1.7mm DFN3030-10B package. A stable and efficient power supply circuit can be configured by simply adding only two ceramic capacitors externally thereby contributing to PCB space saving and the shortening of development time.

Integration of the coil simplifies the board layout and minimises any unwanted radiated noise. The XCL231 can operate from 3.0V~36.0V and deliver loads up to 600mA. It’s designed for very high efficiencies at low output loads, with low quiescent current.

The XCL231 includes a current limit fold-back circuit, adjustable soft-start and a power good output. In addition, an innovative Copper “CoolPost” structure provides improved thermal performance by more than 30%.
