DESCRIPTION
The MSA240 is a surface mount constructed PWM amplifier that provides a cost effective solution in many industrial applications. The MSA240 offers outstanding performance that rivals many much more expensive hybrid components. The MSA240 is a complete PWM amplifier including an oscillator, comparator, error amplifier, current limit comparators, 5V reference, a smart controller and a full bridge output circuit. The switching frequency is user programmable up to 50 kHz. The MSA240 is built on a thermally conductive but electrically insulating substrate that can be mounted to a heatsink.
