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 allowing smaller sized components. The output voltage level .
• 4.75V to 26V supply voltage operating.
• Efficiency up to 85%.
• Typical frequency operation to 1MHz.
• Voltage-mode PWM step-down regulation.
• 1V±2% internal reference.
• Shutdown current less than 30uA.
• Soft-start built-in.
• Short-circuit protection build-in
• QFN-16 & SOP-14 package.
Applications
•DC-DC power management.
