LP873344RHDRQ1 General Description

One of the standout features of the LP873344RHDRQ1 is its automatic PWM/PFM operation in AUTO mode, which ensures high efficiency across a wide output-current range. Additionally, the device supports remote voltage sensing to compensate for IR drop, enhancing output voltage accuracy. The ability to force the switching clock into PWM mode or synchronize it with an external clock helps minimize disturbances in the system

Key Features

Compact design enables reduced PCB area usage
Ultra-low noise and high PSRR ensure reliable operation
Silicon-reliable construction for harsh environments
