ADP1606 2 MHz, Synchronous Boost DC-to-DC Converters _ BDTIC a Leading Distributor in China

ADP1606 2 MHz, Synchronous Boost DC-to-DC Converters

The ADP1606/ADP1607 are high efficiency, synchronous, fixed frequency, step-up dc-to-dc switching converters with a 1.8 V fixed output voltage option and a 1.8 V to 3.3 V adjustable output voltage option for use in portable applications.

The 2 MHz operating frequency enables the use of small footprint, low profile external components. Additionally, the synchronous rectification, internal compensation, internal fixed current limit, and current mode architecture allow excellent transient response and a minimal external part count.

Other key features include fixed PWM and light load PFM mode options, true output isolation, thermal shutdown (TSD), and logic controlled enable. Available in a lead-free, thin, 6-lead LFCSP package, the ADP1606/ADP1607 are ideal for providing efficient power conversion in portable devices.
