R1278 Series of 36V Synchronous Step-Down DC/DC Converters with Built-in Drivers for Automotive and Industrial Applications
Ricoh Electronic Devices has presented the R1278 arrangement, a 36V most extreme evaluated coordinated advance down DC/DC converters with worked in drivers for both car and mechanical applications.
This new gadget has a working recurrence at 2 MHz and effectiveness of 87% and keeps up the yield voltage steady when there is a drop-in info voltage by diminishing a changing recurrence to the base of 1/4. The Interference impact of the AM band is little as the gadgets accomplish EMI commotion decrease by utilizing a spread range clock generator.
