LM3102 SIMPLE SWITCHER廬 Synchronous 1MHz 2.5A Step-Down Voltage Regulator
September 2007
LM3102
SIMPLE SWITCHER廬 Synchronous 1MHz 2.5A
Step-Down Voltage Regulator
General Description
The LM3102 Synchronously Rectified Buck Converter fea-
tures all required functions to implement a highly efficient and
cost effective buck regulator. It is capable of supplying 2.5A
to loads with an output voltage as low as 0.8V. Dual N-Chan-
nel 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. It requires no loop compensation, re-
sults in a fast load transient response and simple circuit
implementation. The operating frequency remains nearly con-
stant with line variations due to the inverse relationship be-
tween the input voltage and the on-time. The operating
frequency can be externally programmed up to 1 MHz. Pro-
tection features include V
CC
under-voltage lock-out, output
over-voltage protection, thermal shutdown, and gate drive
under-voltage lock-out. The LM3102 is available in the ther-
mally enhanced eTSSOP-20 package.
