Title:
ON-VEHICLE ELECTRONIC CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2020088963
Kind Code:
A
Abstract:
To improve the boosting efficiency of a booster circuit unit built into an on-vehicle electronic control device and suppress the heat generation of a switching control element for boosting.SOLUTION: A switching control element 134 includes a high-speed operation first element 134a and a highly conductive second element 134b connected in parallel, and includes a time difference control circuit 140 that generates a first gate signal GT1, and then generates a second gate signal GT2 after a second closing delay time Ton has elapsed when a drive signal output circuit 138 generates a drive signal voltage GT0, and stops a second gate signal GT2, and then stops the first gate signal GT1 after a first opening delay time Toff has elapsed when the driving signal voltage GT0 is stopped, and the first element 134a shares switching transient loss and the second element 134b shares closed circuit conduction loss.SELECTED DRAWING: Figure 1
