MIC2130/1

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.

• 8V to 40V input voltage range

• Adjustable output voltages down to 0.7V

• LOW EMI option MIC2131

• Fixed 150kHz and 400kHz frequency options

• Excellent line and load regulation due to fast hysteretic

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.

control loop during transients

• Adaptive gate drive allows efficiencies over 95%

• Programmable current limit with no sense resistor

• Senses low-side MOSFET current

• Internal drivers allow 15A output current

• Power Good output allow simple sequencing

• Programmable soft-start pin

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.

• 100% increase in current limit (MIC2131)

• Output over-voltage protection

The MIC2130/1 is available in small size 16-pin 4mm x

4mm MLF^®package, as well as 16-pin e-TSSOP at a

junction temperature range of –40°C to +125°C.

• Programmable Input UVLO

• 16-pin e-TSSOP and 16-pin 4mm x 4mm MLF^®

• Junction temperature range of –40°C to +125°C
