3 Description
The LM73605-Q1/LM73606-Q1 family of devices are
easy-to-use
synchronous
step-down
DC-DC
converters capable of driving up to 5 A (LM73605-
Q1) or 6 A (LM73606-Q1) of load current from a
supply voltage ranging from 3.5 V to 36 V. The
LM73605-Q1/LM73606-Q1
provide
exceptional
efficiency and output accuracy in a very small
solution size. Peak current-mode control is employed.
Additional features such as adjustable switching
frequency, synchronization to an external clock,
FPWM option, power-good flag, precision enable,
adjustable soft start, and tracking provide both flexible
and easy-to-use solutions for a wide range of
applications. Automatic frequency foldback at light
load and optional external bias improve efficiency
over the entire load range. The family requires few
external components and has a pinout designed for
simple PCB layout with optimal EMI and thermal
performance. Protection features include thermal
shutdown, input undervoltage lockout, cycle-by-cycle
current limiting, and hiccup short-circuit protection.
The LM73605-Q1 and LM73606-Q1 devices are pin-
to-pin compatible for easy current scaling.
