MIC2253 - 3.5A 1MHz High Efficiency Boost Regulator

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.

Key Features

  • 3.5A minimum switch current 1.245V ± 3% feedback voltage 2.5V to 10V input voltage Output over-voltage protection (OVP) Externally programmable soft-start Output voltage up to 30V (max) Fixed 1MHz operation.

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.
