AIC1622 General Description
The AIC1620/AIC1621/AIC1622 are high efficiency step up DC-DC converter. The start-up voltage is as low as 0.8V and operate with an input voltage down to 0.7V. Consuming only 20A of quiescent 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 depends on the load and the input voltage can range up to 500KHz.The peak current of the internal switch is fixed at 0.8A (AIC1620), at 0.45A (AIC1621), or is selectable (AIC1622) for design flexibility. Ripple does not exceed the product of the switch current limit and the filter capacitor equivalent series resistance (ESR). The AIC1622 also features a circuit that eliminates noise due to inductor ringing.
