1.2MHz, 2.5A, 24V Output Boost Converter



GENERAL DESCRIPTION

The MA2013 is a constant frequency, current mode boost converter intended for

small, low power applications. The MA2013 input voltage ranging is from 2.3V to 12V. The

1.2MHz switching frequency allows small external inductors. Internal power MOSFET with

low RDS(ON) provides high efficiency. Internal soft-start function prevents inrush current and

extends battery life.

The MA2013 also requires protection functions such as input Under-Voltage Lock-Out,

current limit and thermal shutdown to prevent IC damage. The MA2013 is available in a small

SOT23-6L package.
