Features & Applications

The MIC2185YQS TR is a high efficiency synchronous boost PWM control IC. With its wide input voltage range of 2.9 V to 14 V, the MIC2185 can be used to efficiently boost voltages in 1- or 2-cell Li Ion battery powered applications, as well as fixed 3.3 V and 5 V systems. Its powerful 5 Ohm output drivers allow the MIC2185 to supply large output currents with the selection of the proper external MOSFETs.

The MIC2185 also features a low current shutdown mode and a programmable undervoltage lockout. A skipped pulse mode of operation can be manually set to achieve higher efficiencies at light load conditions.

Features:

  • Input voltage range: 2.9 V to 14 V
  • 95% efficiency
  • Oscillator frequency of 200kHz/400kHz
  • Frequency sync to 600kHz
  • 0.5 µA shutdown current
  • Two 5 Ohm output drivers
  • Front edge blanking
  • PWM Current Mode Control
  • Cycle-by-Cycle current limiting
  • Frequency foldback protection
  • Adjustable under-voltage lockout
  • Precision 1.245 V reference output
  • 16 pin SOIC narrow body package and 16 pin QSOP package

Applications:

  • 3.3 V to 5 V conversion in telecom systems
  • Satellite Phones
  • Cable Modems
  • 1-and 2-cell Li Ion battery operated equipment
