DescriptionThe LM3102-Q1 synchronously rectified buck converter features all required functions toimplement a highly efficient and cost-effective buck regulator. The device can supply 2.5 A toloads with an output voltage as low as 0.8 V. Dual N-channel synchronous MOSFET switches allow alow component count, thus reducing complexity and minimizing board size.
Different from most other COT regulators, the LM3102-Q1 does not rely on output capacitorESR for stability and is designed to work exceptionally well with ceramic and other very low-ESRoutput capacitors. The device requires no loop compensation, results in a fast load transientresponse and simple circuit implementation. The operating frequency remains nearly constant withline variations due to the inverse relationship between the input voltage and the ON-time. Theoperating frequency can be externally programmed up to 1MHz. Protection featuresinclude VCC undervoltage lockout (UVLO), output overvoltage protection,thermal shutdown, and gate-drive UVLO. The LM3102-Q1 is available in the thermally enhanced 20-pinHTSSOP package.
