XC9802

      The XC9802 is designed as fixed regulated voltage step-up charge pump ICs which provide stable, highly efficient, positive voltages with the only external components required being 2 capacitors.Its typical applications include palm top computers, PDAs, on board local power supplies and various battery powered devices.
      XC9802 has four features. The first one is about its input voltage range which would be from 1.8V to 5.5V. The next one is about its output voltage range which would be from 2.5V to 5.2V. The next one is about its small input current which would be 80A (no load:XC9802). The next one is about its output current which would be 80mA (3.6V - 5V step-up). The next one is about its oscillator frequency which would be 300kHz. The next one is about its stand-by current (CE 'L') which would be 2.0A (max). The next one is that XC9802 can be used as a Step-Up Doubler (sense = 0V). The next one is that it would have MSOP-8A and USP-8 package. That are all the main features.
      Some absolute maximum ratings of XC9802 have been concluded into several points as follow. The first one is about its Vin pin voltage which would be from -0.3 to 6V. The next one is about its Vout pin voltage which would be from -0.3 to 12V. The next one is about its C1 + pin voltage which would be from -0.3 to Vout + 0.3V. The next one is about its C1 - pin voltage which would be from -0.3 to Vout + 0.3V. The next one is about its CE pin voltage which would be from -0.3 to Vin + 0.3V. The next one is about its Vout pin output current which would be 200mA. The next one is about its power dissipation which would be 150mW for MSOP-8A. The next one is about its operating temperature which would be from -40 to +85°C. The next one is about its storage temperature which would be from -40 to +125°C. And so on.
