MAX1809

The MAX1809 is an integrated product combining the PWM controller, FETs and the error amplifier. It is suitable for lower currents (up to 3A) and therefore has more limited applications since the design is not scalable. Input voltages are from 3.3-5.5V.

FAN5236

The FAN5236 from Fairchild Semiconductor is avalable in a QSOP28 packag. It provides a single chip solution for both VDDQ and Vtt. Though featured in PCIM, September 2001, there is no datasheet available yet on the web.
