Dual-output step-down µModule regulator delivers 13 A per channel or 26 A as a single output. The regulator operates from a 4.5 V to 26.5 V input range and supports 0.5 V to 5.5 V outputs. A 400 kHz PMBus-compliant I2C interface provides digital control, sequencing, margining, telemetry, and EEPROM fault logging. The RoHS SAC305 BGA package is rated for an internal operating temperature range of -40 °C to 125 °C.
