18-V multi-channel synchronous buck converter (TPS65400)

TI's four-channel buck DC/DC converter with PMBus/I2C digital interface is well-suited for applications in space-constrained equipment that experience high ambient operating temperature without cooling, such as small cell base stations, infotainment and solid state devices. The TPS65400 dual- or quad-output configurable DC/DC converter integrates eight power MOSFETs and features industry-leading efficiency at up to 95-percent in the smallest footprint.
