Shown in this slide are the output voltage ripple characteristics when using the Torex XCL206 DC/DC converter at several load conditions. The Torex converter transitions into Pulse Frequency Modulation (PFM) operation from Pulse Width Modulation (PWM) operation when load current is low, maintaining low ripple characteristics even when PFM operation is used. The switching of operation modes is very smooth when using the Torex XCL206 DC/DC converter.
