MYMGK1R806FRSR/MYMGK00506ERSR
MonoBK™, 6A DC-DC Converter Series
PRODUCT OVERVIEW
The MYMGK1R806FRSR/MYMGK00506ERSR are miniature
MonoBK™ called “Mono Block”, non-isolated Point-of-Load
(PoL) DC-DC power converters for embedded applications.
The small form factor measures only 9.0 x 7.5 x 5.0 mm.
Applications include powering FPGA/CPU’s, datacom/telecom
systems, Distributed Bus Architectures (DBA), programmable
logic and mixed voltage systems.
The converters have input voltage ranges of 4.5 to 8.0Vdc
(MYMGK1R806FRSR) or 8.0 to 15.0Vdc
(MYMGK00506ERSR) and a maximum output current of 6A.
Based on a fixed frequency synchronous buck converter
switching topology, this high power conversion efficient PoL
module features settable output voltage 0.7 to 1.8Vdc
(MYMGK1R806FRSR) or 0.7 to 5.0Vdc (MYMGK00506ERSR),
On/Off control and Power Good signal output.
These converters also include under voltage lock out (UVLO),
output short circuit protection and over-current protection.

1.All specifications are at typical line voltage, Vout = typ. and full load, +25degC unless otherwise noted. Output capacitors are 100uF x 4 or 220uF x 2 ceramic.
Input capacitors are 47uF x 2 or 22uF x 2 ceramic and plenty electrolytic capacitors. See detailed specifications Input and Output capacitors are necessary for our
test equipment.
2.Use adequate ground plane and copper thickness adjacent to the converter.
