Description

The LM3103MH is a synchronously rectified Buck Converter features all required functions to implement a highly efficient and buck regulator. It is capable of supplying 0.75A to loads with an output voltage as low as 0.6V. Dual N-channel synchronous MOSFET switches allow a low component count, thus reducing complexity and minimizing board size. Different from most other COT regulators, the LM3103 does not rely on output capacitor ESR for stability and is designed to work exceptionally well with ceramic and other very low ESR output capacitors. It requires no loop compensation, results in a fast load transient response and simple circuit implementation. The operating frequency remains nearly constant with line variations due to the inverse relationship between the input voltage and the on-time. The operating frequency can be externally programmed up to 1MHz. Protection features include VCC undervoltage lockout, output overvoltage protection and thermal shutdown.
