DESCRIPTION
he AIC2893 is an adaptive on time control syn-chronous step down converter. The AIC2893 en-ables system designers to complete various power bus regulators with a cost effective, low component count, low standby current.
The AIC2893 main control loop uses adaptive on time control that provides a fast transient re-sponse without external compensation compo-nent. The low impedance internal MOSFETs support high efficiency operation with wide input voltage range form 4.5V to 30V.
The AIC2893 has a proprietary circuit that the device adapts to all ceramic capacitors. The out-put voltage can be adjustable between 0.8V to 6V. The device also features a programmable soft start time.
This device is available in SOP-8 with exposed pad package and provides a very compact sys-tem solution with minimal external components and PCB area.
