Product Summary

AIC1896 is a current-mode pulse-width modulation (PWM), step-up DC/DC Converter. The built-in high voltage N-channel MOSFET allows AIC1896 for step-up applications with up to 30V output voltage, s well as for Single Ended Primary Inductance Converter (SEPIC) and other low-side switching DC/DC converter. The AIC1896 is available in a space-saving SOT-23-6 and TSOT-23-6 package. Applications of the AIC1896 include: White LED Backlight, OLED Driver and LCD Bias.
