AIC1896 1.4MHz SOT23 Current-Mode Step-Up DC/DC Converter FEATURES Fixed Frequency 1.4MHz Current-Mode PWM Operation. Adjustable Output Voltage up to 30V. Guaranteed 13V/ 200mA Output with 5V Input. 2.5V to 10V Input Range. Maximum 0.1µA Shutdown Current. Programmable Soft-Start. Tiny Inductor and Capacitors are allowed. Space-Saving SOT-23-6 Package. APPLICATIONS White LED Backlight. OLED Driver. DESCRIPTION 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, as well as for Single Ended Primary Inductance Converter (SEPIC) and other low-side switching DC/DC converter. The high switching frequency (1.4MHz) allows the use of small external compone [ ... ]
