Features and Benefits
- Up to 96% efficiency
- 0.8 V to VOUT input voltage range
- Low 0.9 V input start-up voltage
- 1.8 V fixed output voltage
- 23 μA quiescent current
- Fixed pulse-width modulation (PWM) and light load pulse frequency modulation (PFM) mode options
- Synchronous rectification

The ADP1606/ADP1607 are high efficiency, synchronous, fixed frequency, step-up dc-to-dc switching converters with a 1.8 V fixed output voltage option and a 1.8 V to 3.3 V adjustable output voltage option 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 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 ADP1606/ADP1607 are ideal for providing efficient power conversion in portable devices.
- 1-cell and 2-cell alkaline and NiMH/NiCd powered devices
- Portable audio players, instruments, and medical devices
- Solar cell applications
- Miniature hard disk power supplies

Evaluation Kits (1)
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-EVALZ). 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.
