General Description
The AP1601 is a high efficiency step-up DC/DC converter for applications using 1 to 4 Ni MH battery cells. Only three external ponents are required to deliver a fixed output voltage of 3.3V or 5V. The AP1601 starts up from less than 0.9V input with 1m A 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 pared with the circuits operating in PSM mode. The PFM control circuit operating in 100KHz (max.) switching rate results in smaller passive ponents. The space saving MSOP packages make the AP1601 an ideal choice of DC/DC...
