ADP1607-EVALZ: 3.3V @ 900mA, 0.9 ~ 3.3V in

The ADP1607 evaluation board is a complete step-up, dc-to-dc switching converter application with components selected to allow operation over the full input voltage and load ranges for VOUT = 3.3 V. The boost converter is set to transition automatically between PFM and PFM (ADP1607-EVALZ) or fixed to operate in PWM mode only (ADP1607-001-EVALZ). The evaluation boards can be adjusted for different output voltages by changing the feedback resistors, R1 and R2.

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.

This user guide includes I/O descriptions, setup instructions, and the schematic and PCB layout drawings for the ADP1607 step-up converter evaluation board.
