M8088IAAC

M8088IAAC is a fixed-frequency, current-mode synchronous buck converter. The device integrates a main switch and synchronous rectifier, achieving high efficiency without an external Schottky diode. It is ideally suited for powering portable devices from a single-cell lithium-ion battery. The output voltage is adjustable down to 0.6V. The M8088IAAC also operates at 100% duty cycle for low dropout operation, extending battery life in portable systems. The device offers two operating modes: PWM control and PFM mode switching control, enabling high efficiency over a wider load range. The M8088IAAC is available in a thin 5-pin SOT package and is offered in an adjustable version.
