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
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.
0.8 V to VOUT input voltage range
Low 0.9 V input start-up voltage
1.8 V to 3.3 V output voltage range
23 µA quiescent current
Fixed PWM and light load PFM mode options
Synchronous rectification
True shutdown output Isolation
Internal soft start, compensation, and current limit
2 mm × 2 mm, 6-lead LFCSP
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.
