CAUTION: Stresses above those listed in "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.

The EL7571 is a fixed frequency, current mode, pulse width modulated (PWM) controller with an integrated high precision reference and a 5 bit Digital-to-Analog Converter (DAC). The device incorporates all the active circuitry required to implement a synchronous step down (buck) converter which conforms to the Intel Pentium^® II VRM specification. Complementary switching outputs are provided to drive dual NMOS power FET's in either synchronous or non-synchronous configurations, enabling the user to realize a variety of high efficiency and low cost converters.
