APPLICATION NOTE 
AN003_MPT11210IL Evaluation Board User Guide

  

Introduction 

The  MPT11210IL  are  fully  integrated  step  down  DCDC  converters  with  control,  gate  drive,  compensation, 
MOSFET switches, and high performance magnetics. They come in an advanced 11mm x 11mm x 4.59mm 76-
pin open frame package, and require only a small number of external components to make complete converter 
solutions. This user guide should be used together with the latest MPT11210IL datasheets for detailed Output 
Voltage, Switching Frequency, and Compensation settings. 

 

The following are the features of this evaluation board. 

 

Populated with one MPT11210IL. 

 

Pads are available for a wide range of input and output capacitor configurations. 

 

Output voltage programming is accomplished via a simple resistor divider. Jumpers are

 

provided for 5 pre-configured output settings. These settings are as follows:

 

0.6V, 1.2V, 1.8V, 3.3V, 5.0V. For output voltage settings other than the pre-configured options, please 
refer to the “

Setting Output Voltages

” section in this user guide. 

 

Switching Frequency programming is accomplished via a simple pulldown resistor. Jumpers are

 

provided for 3 pre-configured frequency settings. These settings are as follows:

 

550kHZ, 750kHZ, 900kHZ, where 550kHZ is the default setting with no jumper installed. For switching 
frequency settings other than the pre-configured options, please refer to the “

Setting Switching 

Frequencies

” section in this user guide. 

 

An internal ramp generator can be adjusted for system stability via a simple pulldown resistor. Jumpers 
are provided for 5 pre-configured compensation settings. Please refer to the “

Setting VRAMP

” section 

in this user guide. 

 

Easy jumper setting for Enable and Disable Functions. 

 

Numerous test points are provided as well as clip leads for input and output connections. 

 

The board comes with input decoupling.
