MIC2253-06YML EVALUATION BOARD
- Refer to User Guide.
Overview
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 4cell NiCad, NiMH, Alkaline or lithium batteries. Maximum battery life is assured with a low 0.1μA shutdown current.
N/A
The MIC2253 Evaluation board requires a single 10W bench power source adjustable from 2.5V to 10V. The load can either be active (electronic load) or passive (resistor) with the capability to dissipate 7W. It is ideal to have an oscilloscope available to view the circuit waveforms, but not essential. For the simplest test, two voltage meters are required to measure input and output voltage. For efficiency measurements, two voltage meters and two ammeters are required to prevent errors due to measurement inaccuracies.
