Certified NET1, NET2 and TBR2 Compliant, Report No.: TBR2/050101/02, TBR2/051501/02 1.2MHz Boost Switching Regulator for 3.3V to 5V Conversion On-Chip Cable Termination Complete DTE or DCE Port with LTC2844 or LTC2845 Small Footprint Available in 36-Lead SSOP (0.209 Wide) Package The LTC®2846 is a 3-driver/3-receiver multiprotocol transceiver with on-chip cable termination. When combined with the LTC2844 or LTC2845, this chip set forms a complete software-selectable DTE or DCE interface port that supports the RS232, RS449, EIA530, EIA530-A, V.35, V.36 and X.21 protocols. All necessary cable termination is provided inside the LTC2846. The LTC2846 has a boost regulator that takes in a 3.3V input and switches at 1.2MHz, allowing the use of tiny, low cost capacitors and inductors 2mm or less in height. The 5V output drives an internal charge pump that requires only five space-saving surface mounted capacitors. The LTC2846 is available in a 36-lead SSOP surface mount package. , LTC and LT are registered trademarks of Linear Technology Corporation.
