IS6806A is an integrated power-level solution optimized for low-duty cycle synchronous step-down applications. It provides high current, high efficiency and excellent thermal performance with high power density. IS6806A The 5 mm x 6 mm MLP package enables the VR design to reach 75 A of current per phase. Internal power MOSFET minimizes the switching and conduction loss.

IS6806A Internal MOSFET gate with high current drive capability, adaptive dead zone time control and integrated bootstrapping switch, thermal monitor, can alert the system when the temperature is too high. The drive is also compatible with various PWM controllers and supports 3.3 V and 5 V PWM. The diode simulation mode can be enabled under light load by using the GLCTRL signal. The device also incorporates a current monitor to provide a real-time current monitoring function (Imon) (the output inductive current is scaled down). This device also integrates fault alarms, such as HS FET overcurrent, overmild HS MOSFET short circuit failure.
