• 20uA Quiescent Supply Current.
• Power-Saving Shutdown Mode (0.1uA typical).
• Internal Synchronous Rectifier (No External Di-ode Required).
• On-Chip Low Battery Detector.
• Low Battery Hysteresis
• Space-Saving Package: MSOP-8

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 20uA 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 efficiency 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, con-necting 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 (AIC1610) or 0.65A (AIC1611) for design flexibility.
