MIC2253
3.5A 1MHz High Efficiency
Boost Regulator with OVP and Softstart General Description Features 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 0.1ВµA shutdown current.
The MIC2253 is available in a low profile 12-pin 3mm x
3mm MLFВ© package. 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.
