The Microchip 3.5A 1MHz High Efficiency Regulator is a high power density 1MHz PWM DC to DC boost regulator. The 3.5A minimum switch current limit combined with a 1MHz switching frequency allows it to use smaller inductors and deliver high power in a tiny solution size. Maximum battery life is assured with a low 0.1μA shutdown current. To prevent a high inrush current, a minimum 1ms soft start period is set by default and it has the ability to extend the soft start period with an external capacitor.
