Low Noise, Step-Up PWM DC/DC Converter

The AIC1880 is a step-up DC/DC converter with a 1.6A, 0.3Ohm internal power switch. A soft-start pro-grammed with an external capacitor sets the input current ramp rate. Pin-selectable high switching frequency (640kHz or 1.2MHz) allows easy filter-ing and low noises. An external compensation pin giv • 90% High Efficiency\n• 1.6A, 0.3Ohm, 12V Internal Power MOSFET\n• 640kHz/1.2MHz Pin-Selectable Operation Frequency\n• 2.6V to 5.5V Input Range\n• Low Shutdown Current: 0.1mA\n• Programmable Soft-Start\n• External Compensation Network\n• Adjustable Output from VIN to 11V\n• Thin MSOP-8 Package;
