... Operation Description The FAN8060 is a step-down converter operating in current-mode PWM architecture with a typical switching frequency of 1.2MHz. At the beginning of each clock cycle, the P-channel transistor is turned on. The current in the inductor ramps up and is sensed via an internal circuit. The P-channel switch is turned off when the ...
