Introduction

Micrel’s MIC2199 is a high power 300kHz synchronous buck

DC-DC controller housed in a small 4mm x 4mm MLF™

12-lead package. The MIC2199 operates from a wide 4.5V to

32V input and can be programmed for output voltages from

0.8V to 6V. The wide input voltage capability makes the

MIC2199 an ideal solution for point-of-load DC-to-DC con-

version in 5V, 12V and higher systems.

The 300kHz switching frequency allows the use of small

inductor and small output capacitors. The current mode PWM

control along with external COMP pin allows for ease of

stability compensation and fast transient response across a

wide range of applications.

An all N-Channel synchronous architecture and powerful

output drivers allow up to 20A of output current capability. For

smaller external components, refer to the 500kHz MIC2198.

MIC2199 Evaluation Board Input/Output Voltages and

Load Current

The MIC2199 evaluation board is designed to operate from

a load current of up to 5A. This evaluation board can easily be

modified to handle up to 32V

tor voltage rating; and handle higher load current by parallel-

ing MOSFETs in the Q3 and Q4 slots and lowering the sense

resistor value to handle higher load current. Consult the

MIC2199 data sheet for more information.
