AIC1628

High-Efficiency, Step-Up DC/DC Controller

The AIC1628 is a high performance step-up DC/DC controller, designed to drive an external power switch to generate programmable posi-tive voltages. In the particularly suitable LCD contrast bias and flash memory programming power supply applications, typical full-load effi-ciencies are 85% to 95; ? 4V to 20V Input Voltage Operation.\n? Adjustable Output Voltage.\n? Low Quiescent Current at 100mA.\n? Pulse-Skipping and Pulse-Frequency Modulation Maintain High Efficiency (max. 95%).\n? 90KHz to 250KHz Oscillator Frequency.\n? Power-Saving Shutdown Mode (8uA Typical).\n? Push-Pull Driver Ou;
