XA2317 - Synchronous Boost DC/DC Regulator

Description

The XA2317 is high efficiency synchronous, PWM step-up DC/DC converters optimized to provide a high efficient solution to medium power systems.

The devices work under the input voltage between 0.9V and 4.4V with a 1.4MHz fixed frequency switching.

Features

  • Up to 94% Efficiency ：Low voltage start-up 0.9V Shut-down current: < 1µA ： ～Input voltage 0.9V 4.4V ： ～Output voltage 2.5V 4.3V (Up to 5V with Schottky) ΩLow switch on resistance RDS(ON), Internal switch: 0.35 1.4MHz fixed frequency switching Automatic PWM/PFM mode switching High switch on current: 0.9A Low profile SOT-23-6 package (lead-free packaging is now available).
