APW7057, High Power Step-Down Synchronous DC/DC Controller
The APW7057 is a 300kHz constant frequency voltage mode synchronous switching controller that drives external N-channel MOSFETs.
When the input supply drops close to output, the upper MOSFET remains on, achieving 100% duty cycle.
Internal loop compensation is optimized for f
