General Description
The MSA260 is a surface mount constructed PWM
amplifier that provides a cost effective solution in many
industrial applications. The MSA260 offers outstand-
ing performance that rivals many much more expen-
sive hybrid components. The MSA260 is a complete
PWM amplifier including an oscillator, comparator, er-
ror amplifier, current limit comparators, 5V reference,
a smart controller and a full bridge IGBT output circuit.
The switching frequency is user programmable up to
50 kHz. The MSA260 is built on a thermally conductive
but electrically insulating substrate that can be mount-
ed to a heatsink.
