The device is a 3-A synchronous buck converter that operates from 4.2-V to 18-V input voltage, and 0.6-V to 7-V output voltage. The device employs AECM control, an emulated current control topology that combines the advantages of peak current mode control and D-CAP2 control, providing fast transient response with true fixed switching frequency.
With the proper MODE configurations, the device supports selectable Eco-mode operation or FCCM operation and selectable power good indicator or external soft start.
With an on-time extension function, the device supports a maximum duty cycle of 98%.
