Model Description
Ceramic condenser -compatible pressure promotion DC/DC controller IC ■ Characteristics The XC9104 series is a general -purpose high clock pressure promotion DC/DC converter controller that allows stable operation regardless of the type of load capacitors. By inserting a resistance of about 0.1Ω for current sense, the phase compensation is performed when using a low ESR capacitor. This makes it easy to use ceramic capacitors, which were very difficult, and are very small and low ripples. The tantalized type does not require a current sense resistance as before. The output voltage can be set from 1.5V to 30V with an external resistance (RFB1, 2) with a built -in reference voltage source of 0.9V (accuracy ± 2.0%). The switching frequency is 300kHz or 180kHz, and the external parts can be reduced. 100kHz and 500kHz will also be customized. The PWM/PFM automatic switching type XC9104 series shifts from PWM control to PFM control during light load. This achieves high efficiency in the total load area from light load to large power current. At the time of the standby (CE terminal "L"), the current consumption is reduced to 1.0 μA or less by stopping all circuits.
