GENERAL DESCRIPTION
The ADP1606/ADP1607 are high efficiency, synchronous, fixed
frequency, step-up, dc-to-dc switching converters for use in
portable applications.
The ADP1606/ADP1607 evaluation boards are complete step-up,
dc-to-dc switching converter applications with components
selected to allow operation over the full input voltage and load
ranges. The ADP1606 evaluation board has a 1.8 V fixed output
voltage and requires no external resistors. The ADP1607
evaluation boards are set to transition automatically between
PFM and PWM (ADP1607-EVALZ ) or fixed to operate in
PWM mode only (ADP1607-001-E VA L Z). The ADP1607
evaluation boards can be adjusted for different output voltages
by changing the feedback resistors, R1 and R2.
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.
This user guide includes input/output descriptions, setup
instructions, and the schematics and printed circuit board
(PCB) layout drawings for the ADP1606/ADP1607 step-up
converter evaluation boards.
Complete specifications for the ADP1606/ADP1607 are
available in the ADP1606/ADP1607 data sheet, which should be
consulted in conjunction with this document when using the
evaluation boards.
