LM53625xQEVM and LM53635xQEVM User's Guide
1 Introduction
The LM53635xEVM is specifically designed for automotive applications, providing a fixed output voltage of
5 V, 3.3 V, or an adjustable output voltage at 3.5-A continuous load. The LM53625xEVM is implemented
using the same board and components but with or an IC with current limit set for 2.5 A maximum
continuous load.

All aspects of the LM53625xQEVM and LM53635xQEVM are optimized for the automotive market. An
input voltage range to 36 V eases input surge protection design. Exceptional dropout performance allows
the elimination of a boost stage in many designs for start/stop applications. An open drain RESET output,
with filtering and Power-GOOD delay, provides a true indication of system status. This feature negates the
requirement for additional supervisory circuitry, saving cost, and board space. Seamless transition
between PWM and PFM operation AUTO MODE, along with a low quiescent current, ensures high
efficiency at all loads. The Texas Instruments LM53625QEVM and LM53635xQEVM helps to evaluate the
operation and performance of the LM53625x and LM53635x and is available for order in five variants. See
Table 1 of orderable EVM variants and configuration.
