3 Description
The
LM46000-Q1
regulator
is
an
easy-to-use
synchronous step-down DC-DC converter capable of
driving up to 500 mA of load current from an input
voltage range of 3.5 V to 60 V. The LM46000-Q1
provides exceptional efficiency, output accuracy and
dropout voltage in a very small solution size. An
extended family is available in 1-A and 2-A load
current options in pin-to-pin compatible packages.
Peak current mode control is employed to achieve
simple control loop compensation and cycle-by-cycle
current
limiting.
Optional
features
such
as
programmable switching frequency, synchronization,
power-good flag, precision enable, internal soft start,
extendable soft start, and tracking provide a flexible
and easy-to-use platform for a wide range of
applications. Discontinuous conduction and automatic
frequency modulation at light loads improve light load
efficiency.
The
family
requires
few
external
components and pin arrangement allows simple,
optimum PCB layout. Protection features include
thermal shutdown, VCC undervoltage lockout, cycle-
by-cycle
current
limit,
and
output
short-circuit
protection. The LM46000-Q1 device is available in
the 16-pin HTSSOP (PWP) package (6.6 mm × 5.1
mm × 1.2 mm) with 0.65-mm lead pitch. The device is
pin-to-pin compatible with the LM4360x and LM4600x
families. The LM46000A-Q1 version is optimized for
PFM operation and recommended for new designs.
