DESCRIPTION
The AIC1638 is a high efficiency step-up DC/DC
converter for applications using 1 to 4 NiMH battery
cells. Only three external components are required to
deliver a fixed output voltage of 2.7V, 3.0V, 3.3V, or
5V. The AIC1638 starts up from below 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.
