EL7571
Programmable PWM Controller
The EL7571 is a flexible, high efficiency, current mode, PWM
step down controller. It incorporates five bit DAC adjustable
output voltage control which conforms to the Intel Voltage
Regulation Module (VRM) Specification for Pentium II and
Pentium Pro class processors. The controller employs
synchronous rectification to deliver efficiencies greater than
90% over a wide range of supply voltages and load
conditions. The on-board oscillator frequency is externally
adjustable, or may be slaved to a system clock, allowing
optimization of RFI performance in critical applications. In
single supply operation, the high side FET driver supports
boot-strapped operation. For maximum flexibility, system
operation is possible from either a 5V rail, a single 12V rail,
or dual supply rails with the controller operating from 12V
and the power FETs from 5V.
