XC6367/XC6368 Series PWM Controlled, PWM/PFM Switchable Step-up DC/DC Controllers
The XC6367/XC6368 series are multi‑functional step‑up DC/DC controllers that provide high‑efficiency power conversion using an external transistor, coil, diode and capacitor. They support selectable output voltages from 1.5 V to 6.5 V in 0.1 V increments and offer PWM or PWM/PFM control for light‑load to high‑current operation.
This datasheet includes general descriptions, pin assignments, electrical characteristics, typical application circuits, performance graphs, packaging information, and marking rules, helping designers integrate the controllers into electronic information organizers, portable phones, audio systems, and other power‑supply designs.
