75 V/2 A Peak, Low Cost, High Frequency Half Bridge Driver
DESCRIPTION
SiP41111 is the MOSFET driver, which is designed to sim-
plify the converter design for the topologies, which requires
the high-side switch such as half bridge, two switch forward
and active clamping forward. The high-side and low-side
drivers can be configured to meet different driving require-
ment for these topologies because the high-side and low
side drivers are independent controlled. The built-in boot-
strap diode eliminates the external diode to improve the flex-
ibility PCB layout. The V_DD undervoltage lockout prevents
the abnormal operation.
