AIC2573 DC/DC Controller

The AIC2573 is a voltage mode synchronous buck PWM controller that drives external N-channel power MOSFET using a 300kHz fixed frequency architecure. This device is capable of producing an output voltage as low as 0.8V. It uses external divider to adjust output voltage with the exact right line and .
