LM5085MYX/NOPB General Description

Featuring a nearly constant operating frequency despite line and load variations, the LM5085MYX/NOPB product leverages the inverse relationship between input voltage and on-time. This PFET architecture allows for 100% duty cycle operation and minimal dropout voltage, enhancing overall efficiency. Moreover, the controller supports over-current detection using either the PFET's RDS(ON) or an external sense resistor, further enhancing system reliability and safety

Key Features

Fast Response Time
Compact Package Option
No External Compensation Needed
Precision Voltage Regulation
Wide Input Voltage Range
Soft-start Timer Included
