MIC2253
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 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.
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 perio...
