METHOD AND APPARATUS FOR SYNCHRONOUS BOOST VOLTAGE REGULATORS WITH ACTIVE NEGATIVE CURRENT MODULATION |
摘要 |
A switch-mode synchronous boost voltage regulator is disclosed that includes a boost voltage regulator and an active current modulator. The active current modulator detects a negative current flowing through the high-side switch during a light load condition. When the negative current is detected, the active current modulator is operable to maintain the high-side switch "on" in a linear mode and to limit the negative current to a predetermined current level.
