XC9101DS02SR

The XC9101DS02SR are step-up multiple current and voltage feedback DC/DC controller ICs. Current sense, clock frequencies and amp feedback gain can all be externally regulated.A stable power supply is possible with output currents of up to 3A and output voltage is selectable in 0.1V steps within a 2.2V - 16.0V (±2.5% accuracy) range (internal). Further, a type which has a 0.9V internal reference voltage and which allows output voltage to be set-up freely via the external components is also available (FB type).Switching frequencies can be regulated externally within a range of 100-600 kHz and therefore frequencies suited to your particular application are selectable.

Features of the XC9101DS02SR are:(1)stable operations via current & voltage multiple feedback;(2)unlimited options for peripheral selection;(3)PWM/PFM switching control (XC9102);(4)current protection circuit;(5)low ripple output voltage during light loads (XC9102);(6)ceramic capacitor compatible.

The absolute maximum ratings of the XC9101DS02SR are:(1)EXT pin voltage:-0.3 to +22 V;(2)Isen pin voltage:-0.3 to +22 V;(3)VIN pin voltage:-0.3 to +22 V;(4)CE/SS pin voltage:-0.3 to +22 V;(5)CLK pin voltage:-0.3 to +22 V;(6)CC/GAIN pin voltage:-0.3 to +22 V;(7)VOUT/FB pin voltage:-0.3 to +22 V;(8)EXT pin current:±100 mA;(9)continuous total power dissipation:150 mW;(10)operating ambient temperature:-40 to +85;(11)storate temperature:-40 to +125.
