Description
General part information
LM3102-Q1 Series
The LM3102 Synchronously Rectified Buck Converter features all required functions to implement a highly efficient and cost-effective buck regulator. The device can supply 2.5 A to loads with an output voltage as low as 0.8 V. 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 LM3102 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. The device 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 to1 MHz. Protection features include VCCundervoltage lockout (UVLO), output overvoltage protection, thermal shutdown, and gate drive UVLO. The LM3102 is available in the thermally enhanced HTSSOP-20 package, and LM3102 is also available in a DSBGA low-profile chip-scale package with reduced output current.
