AIC1642 - 3-Pin One-Cell Step-Up DC/DC Converter

Download the AIC1642 datasheet PDF. This datasheet also covers the AIC variant, as both devices belong to the same 3-pin one-cell step-up dc/dc converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The AIC1642 is a high efficiency step-up DC/DC converter for applications using 1 to 4 battery cells.

Only three external components are required to deliver a fixed output voltage of 2.7V, 3.0V, 3.3V, or 5V.

The AIC1642 starts up from less than 0.9V input with 1mA load.

AIC1642 3-Pin One-Cell Step-Up DC/DC Converter ¡½ FEATURES l l l l l l l ¡½ DESCRIPTION The AIC1642 is a high efficiency step-up DC/DC converter for applications using 1 to 4 battery cells. Only three external components are required to deliver a fixed output voltage of 2.7V, 3.0V, 3.3V, or 5V. The AIC1642 starts up from less than 0.9V input with 1mA load. Pulse Frequency Modulation scheme brings optimized performance for applications with light output loading and low input voltages. The output ripple and noise are lower compared with the circuits operating in PSM mode. The PFM control circuit operating in 100KHz (max.) switching rate results in smaller passive components.
