The LM3100 Synchronously Rectified Buck Converter features all functions needed to implement a highly efficient, cost effective
buck regulator capable of supplying 1.5A to loads with voltages as low as 0.8V. Dual 40V N-Channel synchronous MOSFET switches
allow for low external component thus reducing complexity and minimizing board space. The LM3100 is designed to work exceptionally
well with ceramic and other very low ESR output capacitors. The Constant ON-Time (COT) regulation scheme requires no loop
compensation, results in fast load transient response, and simplifies circuit implementation. Through the use of a unique
design the regulator does not rely on output capacitor ESR for stability, as do most other COT regulators. The operating
frequency remains nearly constant with line and load variations due to the inverse relationship between the input voltage
and the on-time. The oprating frequency can be externally programmed up to 1MHz. Protection features include VCC under-voltage lockout, thermal shutdown and gate drive under-voltage lockout. The part is available in a thermally enhanced
eTSSOP-20 package
