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 20A 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 of AIC1610/AIC1611  can be easily set by two external resistors from 1.8V to 5.5V, connecting FB to OUT to get 3.3V, or con-necting to GND to get 5.0V. The peak current of the internal switch is fixed at 1.0A (AIC1610) or 0.65A (AIC1611) for design flexibility.
