TEXAS INSTRUMENTS TPS40055PWPG4 直流/直流控制器, 电压模式, 8V至40V, 1路输出, 同步降压, 1MHz, HTSSOP-16
The is a synchronous step-down Buck Controller offers design flexibility with a variety of user-programmable functions, including soft-start, UVLO, operating frequency, voltage feed-forward, high-side current limit and loop compensation. It uses voltage feed-forward control techniques to provide good line regulation over the wide 4:1 input voltage range and fast response to input line transients. Near-constant modulator gain with input variation eases loop compensation. The externally programmable current limit provides pulse-by-pulse current limit, as well as hiccup mode operation using an internal fault counter for longer duration overloads.
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.
