MP2108
2A, 6V, 740KHz
Synchronous Buck Converter
The Future of Analog IC Technology
DESCRIPTION
The MP2108 is a 2A, 740KHz synchronous
buck converter designed for low voltage
applications requiring high efficiency. It is
capable of providing output voltages as low as
0.9V, and integrates top and bottom switches to
minimize power loss and component count. The
740KHz switching frequency allows for small
filtering components, further reducing the
solution size.
The MP2108 includes cycle-by-cycle current
limiting and under voltage lockout. Internal
power switches, combined with the tiny 10-pin
MSOP or 3mm x 3mm QFN packages, provide
a solution requiring a minimum of board space.
QFN package is recommended if output current
is higher than 1.5A.
FEATURES
2A Output Current
Synchronous Rectification
Internal 160mΩ and 190mΩ Power Switches
Input Range of 2.6V to 6V
Over 95% Efficiency
Under Voltage Lockout Protection
Soft-Start Operation
Thermal Shutdown
Internal Current Limit (Source & Sink)
Tiny 10-Pin MSOP and 3x3 QFN Packages
SOHO Routers, PCMCIA Cards, Mini PCI
Handheld Computers, PDAs
Cell phones, Digital Still and Video Cameras
Small LCD Displays
