... 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 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. 22µH Output 3.3V, 5.0V or Adj. (1.8V to 5.5V) ...

... The lower current limit allows the use of a physically smaller inductor in space-sensitive applications. PFM Control Scheme The key feature of the AIC1610 series is a unique minimum-off-time, constant-on-time, current-limited, pulse-frequency-modulation (PFM) control scheme (see BLOCK DIAGRAM) with the ultra-low quies- PIN 4: REF- 1 ...

... PCB Layout and Grounding Since AIC1610’s switching frequency can range up to 500kHz, it makes AIC1610 become very sensitive. So careful printed circuit layout is im- portant for minimizing ground bounce and noise. IC’s OUT pin should be as clear as possible. ...
