Features & Applications

The MIC9131YM is a current-mode PWM DC-to-DC controller, available in surface mount SOIC-16 package.

This device features a high voltage start-up circuit that allows the device to be connected to input voltages as high as 180 V.  The MIC9131 allows for the designs of high efficiency power supplies. It can achieve efficiencies over 90% at high output currents.

Features:

  • Input voltages up to 180 V
  • Internal oscillator capable of > 2.5 MHz operation
  • Accurate 75% maximum duty cycle
  • Synchronisation capability to 6 MHz
  • Current sense delay of 34 ns
  • Minimum pulse width of <25 ns
  • 90% efficiency
  • 1.3 mA quiescent current
  • 1 μA shutdown current
  • Soft-start
  • Resistor programmable current sense threshold
  • Selectable soft-start retry
  • 4 Ω sink, 12 Ω source output driver
  • Programmable under-voltage lockout
  • Constant-frequency PWM current-mode control
  • 16-pin SOIC and 16-pin QSOP

Applications:

  • Telecom power supplies
  • Line cardsISDN network terminators
  • Micro- and pico-cell base stations
  • Low power (< 100W) dc-dc converters
  • DSL line cards
