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 components.
The Soft-Start function is programmable with an external capacitor, which sets the input current ramp rate.
The AIC1896 is available in a space-saving SOT-23-6 package.
