General Description
Micrel, Inc.
MIC9130
High-Voltage, High-Speed Telecom DC-to-DC Controller
Features
The MIC9130 is a current-mode PWM controller that ef ? ciently
converts –48V telecom voltages to logic levels. The MIC9130
features a high voltage start-up circuit that allows the device to
be connected to input voltages as high as 180V. The high input
voltage capability protects the MIC9130 from line transients
that are common in telecom systems. The start-up circuitry
also saves valuable board space and simpli ? es designs by
integrating several external components.
The MIC9130 is capable of high speed operation. Typically
the MIC9130 can control a sub-25ns pulse width on the gate
out pin. Its internal oscillator can operate over 2.5MHz, with
even higher frequencies available through synchronisation.
The high speed operation of the MIC9130 is made safe by
the very fast, 34ns response from current sense to output,
minimizing power dissipation in a fault condition.
The MIC9130 allows for the designs of high ef ? ciency power

The MIC9130 has a maximum duty cycle of 50%. For de-
signs requiring a high duty cycle, refer to the MIC9131. The
MIC9130 is available in a 16-pin SOP and 16-pin QSOP
package options. The rated junction temperature range is
from –40°C to +125°C.
