Texas Instruments LMZ36002EVM

Overview

LMZ36002EVM from Texas Instruments is an evaluation module designed to accelerate development and validation of the LMZ36002 synchronous buck power module in 12-V to 60-V input industrial and embedded power systems. It supports five selectable output voltages (2.5 V to 7.5 V), five switching frequencies (300 kHz or 500 kHz), full 2-A output current delivery, and provides comprehensive test points for ripple, efficiency, transient response, PWRGD, SS/TR, INH/UVLO, and CLK synchronization.

For engineers reviewing the LMZ36002EVM datasheet, LMZ36002EVM pinout, LMZ36002EVM application, or LMZ36002EVM equivalent, this EVM enables rapid characterization of input/output ripple, line/load regulation, startup/shutdown behavior, Versa-Comp compensation tuning, and bias-source selection under real-world operating conditions with up to 16-AWG wire connections.

Technical Context

The LMZ36002EVM implements the LMZ36002 power module in a fully assembled, thermally optimized PCB layout with integrated input and output capacitors rated for the full 4.5–60-V input and 2.5–7.5-V output ranges. It features dual jumper banks (P1 for V_OUT, P2 for F_SW) and configurable test points for slow-start timing, UVLO threshold adjustment, power-good monitoring, and external clock synchronization.

Test infrastructure includes dedicated scope-accessible nodes (J1, J2) with 0.1-in spaced sockets for low-inductance probing, four AGND reference points for voltage monitoring, and Versa-Comp tuning via J3 plus bias-source selection via J4 - all aligned with the LMZ36002's internal control architecture and compensation flexibility.

FAQ

What is the primary function of the LMZ36002EVM?

The LMZ36002EVM is an evaluation module that enables engineers to rapidly assess the electrical performance, thermal behavior, and feature set of the LMZ36002 synchronous buck power module. It provides pre-configured jumpers for output voltage and switching frequency, accessible test points for key parameters like ripple and efficiency, and a thermally optimized PCB layout - all to accelerate power stage validation before custom board design.

Can the LMZ36002EVM operate across the full input range of the LMZ36002 IC?

Yes, the LMZ36002EVM supports the full 4.5 V to 60 V input voltage range specified for the LMZ36002 IC. Its input capacitor bank and layout are designed to handle this range while maintaining stability and low ripple. The UVLO threshold is approximately 4 V with 0.4 V hysteresis, and minimum operating input is the greater of 4.5 V or (VOUT + 2 V), as confirmed in the LMZ36002EVM User's Guide SNVU476.

How do I configure the output voltage on the LMZ36002EVM?

Output voltage on the LMZ36002EVM is configured using the Vout Select jumper (P1), which sets one of five fixed values: 2.5 V, 3.3 V, 5.0 V, 6.0 V, or 7.5 V. Jumper positions are defined in Table 1 of the LMZ36002EVM User's Guide. Power must be removed before changing P1, and the selected output should be verified with a voltmeter connected to the VOUT test point referenced to AGND.

Does the LMZ36002EVM support external clock synchronization?

Yes, the LMZ36002EVM provides direct access to the CLK pin of the LMZ36002 via the CLK test point. An external clock signal can be applied here to synchronize the module's switching frequency - enabling noise reduction in multi-rail systems or alignment with system timing references. The EVM's layout preserves signal integrity for this interface, and no additional components are required for basic synchronization.

What is the purpose of the Versa-Comp feature on the LMZ36002EVM?

The Versa-Comp feature on the LMZ36002EVM allows tuning of the LMZ36002's internal compensation network via jumper J3 to optimize phase and gain margin for specific output voltage and output capacitance configurations. This eliminates the need for external compensation components and ensures stable operation across varying output capacitor types and values - a key advantage when evaluating different ceramic or polymer capacitor selections during design validation.
