MIC2253

In Production

The MIC2253 is a high power density 1MHz PWM DC/DC boost regulator. The 3.5A minimum switch current limit combined with a 1MHz switching frequency allows the MIC2253 to use smaller inductors and deliver high power in a tiny solution size. The 2.5V to 10V input voltage range of MIC2253 allows direct operation from 1- and 2-cell Li-Ion as well as 3- to 4-cell NiCad, NiMH, Alkaline, or lithium batteries. 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 the MIC2253 has the ability to extend the soft-start period with an external capacitor....
