DESCRIPTION
The AIC1610/AIC1611 are high efficiency
step up DC-DC converters. The start-up volt-
age is as low as 0.8V with operating voltage
down to 0.7V. Simply consuming 20µA of qui-
escent current. These devices offer a built-in
synchronous rectifier that reduces size and
cost by eliminating the need for an external
Schottky diode and improves overall effi-
ciency by minimizing losses.
The switching frequency can range up to
500KHz depending on the load and input volt-
age. The output voltage can be easily set by
two external resistors from 1.8V to 5.5V,
connecting FB to OUT to get 3.3V, or
connecting to GND to get 5.0V. The peak
current of the internal switch is fixed at 1.0A
3-Cell
of
(AIC1610) or 0.65A (AIC1611) for design
flexibility.
