The AIC1880 is a step-up DC/DC converter with a 1.6A, 0.3 internal power switch. A soft-start programmed with an external capacitor sets the input current ramp rate. Pin-selectable high switching frequency (640kHz or 1.2MHz) allows easy filtering and low noises. An external compensation pin gives users flexibility in setting frequency compensation, which makes it feasible to use the small, low ESR ceramic output capacitors. The AIC1880 converts input ranging 2.6V to 5.5V into output voltage up to 11V. The device is available in a low profile 8-lead MSOP package.
