3 Description
–40°C to 150°C junction Temperature Range
The LM53600/01 synchronous buck regulator is
Peak Current Mode Control
optimized for automotive applications, providing either
2.1-MHz (±10%) Fixed Switching Frequency
an adjustable output or an output voltage of 3.3 V or
Pin Selectable Forced PWM Mode
5 V. The LM53600-Q1 device supports load currents
up to 650 mA and the LM536001-Q1 supports load
External Frequency Synchronization With Forced
currents up to 1000 mA.
PWM Mode
Advanced high speed circuitry allows the device to

regulate from an 18-V input to a 3.3-V output at a
Automatic Light Load Mode for Improved
fixed frequency of 2.1 MHz. Innovative architecture
Efficiency
allows the device to regulate a 3.3-V output from an
Built-In Compensation, Soft-start, Current Limit,
input voltage of only 3.8 V. Input voltage range up to
Thermal Shutdown, and UVLO
36 V, with transient tolerance up to 42 V, eases input
surge protection design.
Spread Spectrum is Available as a Factory Option
Electrical Specifications
An open drain reset output, with filtering and delayed
release, provides a true indication of system status.
