High Voltage Synchronous Buck
Control IC with Low EMI Option General Description Features The MIC2130/1 is a high voltage input PWM synchronous
buck controller IC. It is a voltage mode controller with a
fast hysteretic control loop (FHyCL) employed during fast
line and load transients. The internal gate drivers are
designed to drive high current MOSFETs.
The MIC2130/1 can produce output voltages down to 0.7V
with input voltage from 8V to 40V. The MIC2130 family of
control ICs implements fixed frequency PWM control. The
active anti-shoot through drive scheme means a wide
range of external MOSFETs may be used while
maintaining optimum efficiency.
The MIC2131 is the fully functional version of the family
and implements a new feature to minimize EMI. This
function is critical for systems that need to be compliant
with EMI standards throughout the world.
The MIC2130/1 is available in small size 16-pin 4mm x
4mm MLFВ® package, as well as 16-pin e-TSSOP at a
junction temperature range of вЂ“40В°C to +125В°C.
