ADP1606/ADP1607It is a high efficiency, synchronous, fixed frequency, step-up DC-DCSwitching converters, with a fixed output voltage option of 1.8 V and an adjustable output voltage option of 1.8 V to 3.3 V, suitable for portable applications.
The 2 MHz operating frequency allows the use of small, thin external components. In addition, synchronous rectification, internal compensation, internally fixed current limit, and current-mode architecture ensure excellent transient response and minimal external component count.
Other key features include fixed PWM and light load PFM mode options, true output isolation, thermal shutdown (TSD), and logic control enable. The ADP1606/ADP1607 are available in a lead-free, thin 6-lead LFCSP package for high efficiency and power savings in portable devices.
