DC/DC converter optimised for low load efficiency
ON Semiconductor has introduced the LV5980MC, a 3A step down dc/dc converter ic designed to improve conversion efficiency at light load.
In consumer electronics designs, the device is capable of reducing energy consumption during standby mode. It regulates input voltages from 4.5 to 23V down to an output voltage as low as 1.235V.
Combining a low consumption power saving feature, with both pwm and pfm, the device can achieve 80% efficiency at an output current of 2mA in typical applications.
It also includes an internally fixed switching frequency of 370kHz, high side mosfet of 100mO and is able to supply up to 3.0A of load current.
