Qualified for automotive applications
The LM53600-Q1 and LM53601-Q1 synchronous
buck regulator devices are optimized for automotive
applications, providing an output voltage of 5 V, 3.3 V,
or an adjustable output. Load current up to 650 mA
is supported by the LM53600-Q1, while the LM53601-
Q1 supports up to 1000 mA. Advanced high-speed
circuitry allows the LM53600-Q1 and LM53601-Q1
devices to regulate from an input of 18 V to an output
of 3.3 V at a fixed frequency of 2.1 MHz. Innovative
architecture allows the device to regulate a 3.3-V
output from an input voltage of only 3.8 V. The input
voltage range up to 36 V, with transient tolerance of
up to 42 V, eases input surge protection design. An
open drain reset output, with filtering and delayed
release, provides a true indication of system status.
This feature negates the requirement for an additional
supervisory component, saving cost and board space.
Seamless transitions between PWM and PFM modes,
along with a quiescent current of only 23 µA, ensures
high efficiency and superior transient response at all
loads. Few external components are needed allowing
the generation of compact PCB layout. While the
LM53600-Q1 and LM53601-Q1 devices are Q1 rated,
electrical characteristics are ensured across a junction
temperature range of –40°C up to 150°C.
AEC-Q100 qualified with the following results:
– Device temperature grade 1: –40°C to 125°C
ambient operating temperature range
– Device HBM classification level 2
– Device CDM classification level C5
–40°C to 150°C junction temperature range
