The LM3102 Synchronously RecTIfied Buck Converter featuresall required funcTIons to implement a highly efficient andcost effecTIve buck regulator. It is capable of supplying 2.5Ato loads with an output voltage as low as 0.8V. Dual N-Channelsynchronous MOSFET switches allow a low componentcount, thus reducing complexity and minimizing board size.Different from most other COT regulators, the LM3102 doesnot rely on output capacitor ESR for stability, and is designedto work excepTIonally well with ceramic and other very lowESR output capacitors. It requires no loop compensation, resultsin a fast load transient response and simple circuitimplementation. The operating frequency remains nearly constantwith line variations due to the inverse relationship betweenthe input voltage and the on-time. The operatingfrequency can be externally programmed up to 1 MHz. Protectionfeatures include VCC under-voltage lock-out, outputover-voltage protection, thermal shutdown, and gate driveunder-voltage lock-out. The LM3102 is available in the thermallyenhanced eTSSOP-20 package.
