Beschreibung

The ADP1607 is a high efficiency, synchronous, fixed frequency, step-up dc-to-dc switching converter with an adjustable output voltage between 1.8 V and 3.3 V 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 for 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 ADP1607 is ideal for providing efficient power conversion in portable devices.
