MA2200

High Voltage, Boost Controller



GENERAL DESCRIPTION

The MA2200 is a current mode step up controller. The controller input voltage ranging

from 3.5V to 28V. This device is designed to drive an external N-channel MOSFET, Output

voltage is programmable from 1.0V.

The MA2200 switching frequency is 800KHz, allows usage of small external inductors and

capacitors and provides extremely fast transient response. External soft start results in very

low inrush current and extends battery life of portable devices. External power MOSFET with

very low R_DS(ON)provides high efficiency and good product reliability. The controller also

provides protection functions such as input under voltage lock-out(UVLO), output over voltage

protection (only in SOP8L), current limit and thermal shutdown.
