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.
