TEXAS INSTRUMENTS LM25085MY/NOPB 控制器, PFET, 恒定通导时间, 4.5V至42V, 1路输出, 降压, 1MHz, MSOP-8
The is a high efficiency PFET Switching Regulator 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 42V input range. The constant on-time regulation principle requires no loop compensation, simplifies circuit implementation and results in ultra-fast 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.
