GENERAL DESCRIPTION
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 Guaranteed by design, but not production tested. VIN can never exceed VOUT once the ADP1606/ADP1607 is enabled.
2 Minimum value is characterized by design. Maximum value is characterized on the bench.
3 This parameter is the semiconductor leakage current. The semiconductor leakage current doubles with every 10°C increase in temperature. The maximum limit
follows the same trend over temperature.
4 TSD protection is only active in PWM mode.
