EG Micro EG7500

The EG7500 integrates two error amplifiers, an externally adjustable oscillator, a dead-time control comparator, PWM functional control circuitry, a 5V reference voltage with ±1% accuracy, and power transistor output driver circuits.

The common-mode voltage range of the two error amplifiers is -0.3V to Vcc - 2V. The dead-time control comparator produces a fixed offset voltage to generate approximately 5% dead time. The EG7500's output transistors can be configured in either common-emitter or emitter-follower mode, allowing selection between push-pull (double-ended) or single-ended output. In push-pull mode, the two drive pulses are 180° out of phase; in single-ended mode, the two drive pulses are synchronized and in phase.
