AT1793 - 2-Channel Step-Down PWM Controller
AT1793 is a voltage-mode PWM step-down controller capable of driving loads over a wide input supply range with excellent line and load regulation characteristics.
High efficiency is obtained through the use of a low Rds(on) P-channel power switch.
It uses a fixed switching frequency up to 1MHz thus
