Product Details
The LTM8023 is a complete 2A, DC/DC step-down power supply. Included in the package are the switching controller, power switches, inductor, and all support components. Operating over an input voltage range of 3.6V to 36V, the LTM8023 supports an output voltage range of 0.8V to 10V, and a switching frequency range of 200kHz to 2.4MHz, each set by a single resistor. Only the bulk input and output filter capacitors are needed to finish the design.
The low profile package enables utilization of unused space on the bottom of PC boards for high density point of load regulation.
The LTM8023 is packaged in a thermally enhanced, compact and low profile over-molded land grid array (LGA) and ball grid array (BGA) packages suitable for automated assembly by standard surface mount equipment. The LTM8023 is available with SnPb (BGA) or RoHS compliant terminal finish.
Applications
- Automotive Battery Regulation
- Power for Portable Products
- Distributed Supply Regulation
