2 MHz, Synchronous Boost DC-to-DC Converter Data Sheet ADP1607 FEATURES GENERAL DESCRIPTION Up to 96% efficiency The ADP1607 is a high efficiency, synchronous, fixed 0.8 V to V input voltage range OUT frequency, step-up dc-to-dc switching converter with an Low 0.9 V input start-up voltage adjustable output voltage between 1.8 V and 3.3 V for use 1.8 V to 3.3 V output voltage range in portable applications. 23 A quiescent current The 2 MHz operating frequency enables the use of small Fixed PWM and light load PFM mode options footprint, low profile external components. Additionally, the Synchronous rectification synchronous rectification, internal compensation, internal fixed True shutdown output Isolation current limit, and current mode architecture allow for excellent Internal soft start, compensation, and current limit transient response and a minimal external part count. 2 mm 2 mm, 6-lead LFCSP Other key features include fixed PWM and light load PFM Compact solution size mode options, true output isolation, thermal shutdown (TSD), APPLICATIONS and logic controlled enable. Available in a lead-free, thin, 6-lead 1-cell and 2-cell alkaline and NiMH/NiCd powered devices LFCSP package, the ADP1607 is ideal for providing efficient Portable audio players, instruments, and medical devices power conversion in portable devices.
