SNVSAR0 – NOVEMBER 2016 LM53603 (3 A), LM53602 (2 A) 3.5 V to 36 V Wide-VIN Synchronous 2.1 MHz Step-Down
Converters
1 Features 3 Description The LM53603 and LM53602 buck regulators are
specifically designed for 12-V industrial and
automotive applications, providing an adjustable
output voltage from 3.3 V to 10 V at 3 A or 2 A, from
an input voltage of up to 36 V. Advanced high-speed
circuitry allows the device to regulate from an input of
up to 20 V, while providing an output of 5 V at a
switching frequency of 2.1 MHz. The innovative
architecture allows the device to regulate a 3.3-V
output from an input voltage of only 3.5 V. All aspects
of this product are optimized for the industrial and
automotive customer. An input voltage range up to 36
V, with transient tolerance up to 42 V, eases input
surge protection design. An open-drain reset output,
with filtering and delay, provides a true indication of …
