General Description

AIC1634 is a current-mode pulse-width modulation (PWM), step-up DC/DC Converter.

The built-in high voltage N-channel MOSFET allows AIC1634 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.

Key Features

  • Fixed Frequency 1.4MHz Current-Mode PWM Operation. Adjustable Output Voltage up to 30V. Guaranteed 12V/ 150mA Output with 5V Input. 2.6V to 10V Input Range. Maximum 0.1µA Shutdown Current. Programmable Soft-Start. Tiny Inductor and Capacitors are allowed. Space-Saving SOT-23-6 Package. 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 AIC1634 is availab.
