Product Description

The LM3100MH is a SIMPLE SWITCHER® synchronously rectified Buck Converter features all functions needed to implement a highly efficient, 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 operating frequency can be externally programmed up to 1MHz.
