Datasheet Summary
3.5A 1MHz High Efficiency Boost Regulator with OVP and Softstart
General Description
The MIC2253 is a high power density 1MHz PWM DC/DC boost regulator. The 3.5A minimum switch current limit bined 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. The MIC2253 is available in a low profile 12-pin 3mm x 3mm MLF© package. To prevent a high inrush current, a minimum 1ms soft-start...
