TEXAS INSTRUMENTS LM5085MM/NOPB 直流/直流控制器, 恒定通导时间, 4.5V至75V, 1路输出, 降压, 1MHz, MSOP-8
The is a constant on-time non-synchronous PFET Buck Controller can be used to quickly and easily develop a small, efficient buck regulator for a wide range of applications. This high voltage controller contains a PFET gate driver and a high voltage bias regulator which operates over a wide 4.5 to 75V input range. The constant on-time regulation principle requires no loop compensation, simplifies circuit implementation and results in ultrafast load transient response. The operating frequency remains nearly constant with line and load variations due to the inverse relationship between the input voltage and the on-time. The PFET architecture allows 100% duty cycle operation for a low dropout voltage. Either the RDSON of the PFET or an external sense resistor can be used to sense current for over-current detection.
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.
