SC1110 - SINK AND SOURCE DC/DC CONTROLLER FOR TERMINATION POWER SUPPLY APPLICATIONS

General Description

The SC1110 is a low-cost, full featured, synchronous voltage-mode controller designed to generate termination voltage in double data rate (DDR) memory systems and other applications where wide data bus need to be actively terminated.

Key Features

  • include temperature compensated voltage reference, triangle wave oscillator and current sense comparator circuitry, and allows the use of inexpensive N-channel power switches. The SC1110 operates at a fixed 250kHz, providing an optimum compromise between efficiency, transient performance, external component size, and cost.

SINK AND SOURCE DC/DC CONTROLLER FOR TERMINATION POWER SUPPLY APPLICATIONS PRELIMINARY - October 9, 2000 SC1110 TEL:805-498-2111 FAX:805-498-3804 WEB:http://www.semtech.com DESCRIPTION The SC1110 is a low-cost, full featured, synchronous voltage-mode controller designed to generate termination voltage in double data rate (DDR) memory systems and other applications where wide data bus need to be actively terminated. Synchronous control of the MOSFET half bridge allows power flowing bidirectionally. The termination voltage can be tightly regulated to track the chipset voltage, i.e. to be exactly 50% of that at all times. The SC1110 is ideal for low cost implementation of termination voltage supplies.
