... Switching frequencies of 300kHz & 500kHz are also available as custom-designed products. The control of the XC9502 series can be switched between PWM control and PWM/PFM automatic switching control using external signals. Control switches from PWM to PFM during light loads when automatic switching is selected and the series is highly efficient from light loads through to large output currents ...

... XC9502 Series ! Operational Description The XC9502 series are multi-functional, 2 channel step-up and down DC/DC converter controller ICs with built-in high speed, low ON resistance drivers. <Error Amp> The Error Amplifier is designed to monitor the output voltage and it compares the feedback voltage (FB) with the reference voltage. In response to feedback of a voltage lower than the reference voltage, the output voltage of the error amp. decreases. < ...

... XC9502 Series <Setting of Output Voltage> Output voltage can be set by adding external split resistors. Output voltage is determined by the following equation, based on the values of RFB11(RFB21) and RFB12(RFB22). The sum of RFB11(RFB21) and RFB12(RFB22) should normally OUT The value of CFB1(CFB2), speed-up capacitor for phase compensation, should be fzfb × π × CFB1 × RFB11) which is equal to 12kHz ...

... NoteS on Use 1. Checking for Intermittent Oscillation The XC9502 series is subject to intermittent oscillation in the proximity of the maximum duty if the step-down ratio is low (e.g., from 4 3 heavy load is applied where the duty ratio becomes high. Check waveforms at EXT under your operating conditions. A remedy for this problem is to raise the inductance of coil L or increase the load capacitance CL. ...
