Title:
動的オフセット補正を備えるDC/DCコンバータ
Document Type and Number:
Japanese Patent JP2008514177
Kind Code:
A
Abstract:
The present invention provides a DC/DC up-converter (100) that is implemented in form of a switching regulator (100). The DC/DC converter (100) makes use of a switching transistor (104) that controls a charging current for a capacitive element (112). Moreover, the DC/DC converter (100) provides control means (106, 140) to realize an accurate switch-off of the switching transistor (104) at a point of time when the charging current equals zero. Deviations of a first control means (106) are detected by means of a second control means (140) and a corresponding offset control signal (142) is generated for reducing the first control means' offset in a successive duty cycle.
