XC9104 Datasheet Step-up DC/dc Controllers

Manufacturer: Torex Semiconductor

Overview: XC9103/XC9104/XC9105 Series ETR04004-010d Ceramic Capacitor patible, Step-up DC/DC Controllers ☆Green Operation patible.

General Description

The XC9103/XC9104/XC9105 series are PWM, PWM/PFM auto switching /manual switching controlled universal step-up DC/DC converter controllers.

Output will be stable no matter which load capacitors are used but should a low ESR capacitor be used, RSENSE of about 0.1Ω will be required and phase pensation will be achieved.

This allows the use of ceramic capacitors and enables to obtain lower output ripple and small PCB design.
