摘要

Exar Corp's new 5A XRP7704 and 16A XRP7740 quad-PWMrn(pulse-width-modulation)-con-troller chips inciude gate-driver circuitry that drives externalrnFETs. In addition to the four PWM voltage regulators, the devices include a low-dropout linear regulator, which you can use for auxiliary or standby power. The input-voltage range is 6.5 to 20V, and you can set the output voitages at 0.9 to 5V. The four PWM outputs have 12-bit resolution, and the units, which you can program through an I~2C (inter-integrated-circuit) interface, have six general-purpose digi-tal-I/O pins.
