kr Ordering number : ENA0663A Bi-CMOS IC LV5781 Overview 3A, Point-of-load, Chopper-type Step-down Converter The LV5781 is a 1-channel chopper-type (low-side Schottky diode) step-down switching regulator.
It incorporates an 80mΩ (typical) power MOSFET to achieve high-efficiency operation for 3A output currents.
The output voltage is set internally to 3.
3V.
By adding two external resistors, it is possible to set the voltage to any desired setting above 0.
85V.
Inrush current at startup can be prevented by the soft start function.
Using the ON/OFF pins, the converter can be set to standby mode in which the current consumption is 10µA or less.
Both the load and the IC are p...
