TEXAS INSTRUMENTS TPS40425RHAT 直流/直流控制器, PM总线接口, 4.5V至20V, 2路输出, 同步降压, 1.5MHz, VQFN-40
The is a PMBus synchronous Driverless Buck Controller operates in non-smart power mode in factory default setting and it can operate in smart power mode after PMBus programming and power reboot. It can be configured as dual-output or 2-phase. It is also stackable up to 4 phases to support load current as high as 120A. Interleaved phase shift for 2-, 3-, or 4-phases reduce the input and output ripples therefore reducing input and output capacitance. The wide input voltage range can support 5 and 12V intermediate supply buses. The 0.5% reference voltage satisfies the need of precision voltage to the modern ASICs. Using the PMBus standard, the TPS40425 device can program reference voltage, fault limit, UVLO threshold, soft-start time and turn-on and turn-off delay. In addition, the device implements an accurate measurement system to monitor the output voltages, currents and temperatures for individual.
Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
