DESCRIPTION
The AIC2864 is a constant on time control synchronous step down converter. The AIC2864 enables system designers to complete various power bus regulators with a cost effective, low component count, low standby current.
The AIC2864 main control loop uses constant on time control that provides a fast transient response without external compensation component. The low impedance internal MOSFETs support high efficiency operation with wide input voltage range form 4.5V to 16V.
The AIC2864 has a proprietary circuit that the device adapts to all ceramic capacitors. The output voltage can be adjustable between 0.8V to 6V. The device also features a programmable soft start time.
This device is available in SOP-8E package and provides a very compact system solution with minimal external components and PCB area.
