24mΩ/14mΩ Low RDS(ON) internal FETs Wide Input Range: 2.5V to 5.5V Compatible I2C Interface Up to 3.4MHz Up to 6A Output Current Up to 8A Peak Current HCOT Control to Achieve Fast Transient Responses Mode Selection Between PFM and PWM at Light Load Typical 45μA Quiescent Current in Light Load PFM Mode 2.4MHz Switching Frequency Integrated Soft-Start Input UVLO and OVP Build in Thermal Shutdown and OCP 0.1μH Inductor Support I2C address: 0x80 Compact WLCSP-20 Package
TMI31806A is an I2C Programmable, high efficiency, 2.4MHz, Synchronous Buck converter that operates in wide input voltage range from 2.5V to 5.5V. The output Voltage could be programmed from 0.7125V to 1.5V. Very low standby current ensure high efficiency in light load PFM mode. The forced PWM mode could be set to avoid application problems caused by low switching frequency. A HCOT structure is adaptive to achieve the fixed switching frequency and fast load transient response. TMI31806A provides up to 6A output current with Integrated 24mΩ (high side) and 14mΩ (low side) power switch. TMI31806A also implement an internal soft-start and cycleby-cycle over current protection function. In addition, the input UVLO and OVP protection, Thermal shutdown protection.
